* Expose 'inertial scrolling state' in wheel events w3c/pointerevents#587
* question about status of PE3
* follow-up from breakout day session about gestures
* UI events TF meeting



Patrick: still need to catch up with PLH about status of PE3 and how to 
tweak our charter with regards to gestures

Patrick: but I did file our answer to w3c/webai-roadmap#26

Mustaq: question maybe if an AI wants to generate TRUSTED events

<smaug> https://www.w3.org/groups/wg/pointer-events/calendar/

Patrick: i guess at that point, the AI/agent may want to run its own 
headless browser and fake trusted events somehow...

Olli: we need to see if the UI Events TF meeting should still be there 
or removed from calendar

Patrick: there is no UI Events TF as such anymore, is there?

Olli: think Mike Smith was the first person to set this up



# Expose 'inertial scrolling state' in wheel events w3c/pointerevents#587

Mustaq: i have a local patch ready, will send it

<mustaq> Work in progress, expecting to send out a PR in a day or two.

Patrick: opening this up to the the group now, are there any other 
issues you've seen that are worth discussing?

https://github.com/w3c/pointerevents/issues

Mustaq: i think w3c/pointerevents#628 can be closed ... we have those in 
pointer events?

<mustaq> May be close w3c/pointerevents#628 as WAI?

Mustaq: spec probably needs cleanup to not duplicate button info

Olli: makes sense to close yes

Mustaq: looking at w3c/pointerevents#633

Olli: this is about old IE properties

<mustaq> Blink issue: https://crbug.com/40509957

Mustaq: have been discussing if we want to standardise it or not

Olli: is there some rounding happening? old ones integer, modern ones double



# question about status of PE3

<plh> w3c/transitions#779 (comment)

plh: version 3 currently stalled. had a comment on march 13 asking for 
clarification for why certain tests are failing

plh: do we want to go through them right now?

Patrick: can probably start looking now...

<plh> 
https://w3c.github.io/pointereventswg/implementation-reports/wpt-pointerevents-2026-01-25.html#file-26

plh: can we explain why those tests are failing in chrome/firefox? is it 
a test harness limitation, and then if so why is it passing in safari?

mustaq: my understanding is that pen is not well supported at low level 
in webdriver. in some platforms.

mustaq: like a big text box ... if you drag with mouse, it does text 
selection. with touch, it scrolls. with pen, it's not clear/varies by 
platform...

mustaq: so it could be a windows vs macOS with test harness issue

mustaq: safari could be treating pen as mouse inthe webdriver

<plh> 
https://w3c.github.io/pointereventswg/implementation-reports/wpt-pointerevents-2026-01-25.html#file-31

olli: is this the one we discussed recently, where chrome was doing one 
thing, firefox something else...

plh: so is the spec correct, but it's bugs in browsers?

<smaug> 
https://github.com/web-platform-tests/wpt/commit/a9f4351e61506bfec0a0c111f22d164cf213aa1c

mustaq: the test was wrong at some point. we fixed it in november...so 
we believe the test is correct now

plh: do we have bugs filed in chrome/firefox for this?

<mustaq> https://crbug.com/404479707#comment7

<smaug> web-platform-tests/wpt#56614

<mustaq> This behavior is not "fully" specified?

<plh> 
https://w3c.github.io/pointereventswg/implementation-reports/wpt-pointerevents-2026-01-25.html#file-36

mustaq: safari test driver don't support touch

mustaq: safari web driver has limited touch support, but not complete

<plh> 
https://w3c.github.io/pointereventswg/implementation-reports/wpt-pointerevents-2026-01-25.html#file-90

plh: probably same reason as previous one

mustaq: i think we meant to remove all touch-action tests

olli: touch-action none should be supported everwhere. why is it not 
passing in firefox? can't remember, will need to check

plh: could be a corner case if we have a whole bunch of other tests 
passing in firefox

olli: firefox harness doesn't support pen

<mustaq> 
https://wpt.fyi/results/pointerevents/pointerevent_iframe-touch-action-none_touch.html?label=experimental&label=master&aligned

plh: for the test where the behaviour is not fully specified, do we have 
an issue to track that?

olli: for the remove from slot case? yeah there's an issue in WPT, but 
not sure where the issue should go. could even go to DOM spec.

mustaq: what do we do for OUR test though? mark as tentative?

olli: yeah, maybe best to file an issue in our repo

mustaq: so i'll file an issue in our repo

<mustaq> ...and mark the test as tentative on that issue.



# follow-up from breakout day session about gestures

Patrick: can't quite remember what we agreed regarding gestures and charter

plh: i don't think we had fully decided, but my suggestion would be to 
remove mention of gestures from our current rechartering proposal, 
incubate regardless as part of our time, and once we have matured it 
more we can recharter with more concrete proposal

Patrick: what do we need to do to make it official in WICG

plh: i think they need two organisations to lend support

<smaug> mustaq: Why is pointerevent_iframe-touch-action-none_touch.html 
correct? I don't quite understand why Chrome gets that pointercancel. 
Currently I think Firefox and Safari do the right thing. I could be 
missing something.

# UI events TF meeting

Patrick: question we had is whether we still need/want UI events TF 
meeting every month? is there even still a UI events TF as such?

Olli: what happens with the other events, like composition events?

Olli: who is working on the remaining stuff?

plh: you could go to web editing WG and say "should this group take it 
over?" and to the same that PEWG did for mouse/wheel

plh: good thing is that it should be easier to do

plh: for pointer events, do we still have dependency on UI events spec? 
if that spec disappears, would it affect PE?

plh: are we still referencing UI events normatively? yes we are...

plh: and there is still link to keyboard event

olli: that should go to editing WG conceptually

ACTION: Patrick to file an issue on PE about removing reliance 
on/reference to remaining UI events, we can flesh out further

plh: mustaq you should move pointerlock-related things in UI events to 
the pointerlock spec

<smaug> https://w3c.github.io/uievents/#external-pointerlock-algorithms

ACTION: mustaq to look at moving/removing references to UI events 
related to pointerlock spec

mustaq: these are the algos that Gary worked on ... i'll take a look at 
this and update pointerlock

Summary of action items

* Patrick to file an issue on PE about removing reliance on/reference to 
remaining UI events, we can flesh out further
* mustaq to look at moving/removing references to UI events related to 
pointerlock spec
