23978

   -> [17]https://www.w3.org/Bugs/Public/show_bug.cgi?id=23978
   23978 Informing the user shouldn't be optional

     [17] https://www.w3.org/Bugs/Public/show_bug.cgi?id=23978

   JMann: notice that we are still using the word "ring" a lot.

   RS: We could use the word outline instead?

   JMann: I like outline. Don't want to confuse the user by
   referencing ring (the old method name)

   MS: I'll open a new bug on outline

   RS: I don't see anything about this being optional, so that is
   good.
   ... want to check on the scrolling part of this

   <JatinderMann> If the focus region is not on the screen, then
   scroll the region into view when it receives focus.

   JMann: the last sentence of section 3

   RS: do we want it to be similar to scrollPathIntoView?
   ... take a look at the L2 text

   [18]http://www.w3.org/html/wg/drafts/2dcontext/master/

     [18] http://www.w3.org/html/wg/drafts/2dcontext/master/

   <richardschwerdtfeger> Scroll notional child into view with the
   align to top flag set.

   <richardschwerdtfeger> vertical-align:text-top;

   JMann: scroll the region into view by aligning it to the top

   <JatinderMann> If the focus region is not on the screen, then
   scroll the region into view by aligning it to the top when it
   receives focus.

     [19] https://www.w3.org/Bugs/Public/show_bug.cgi?id=23983

   <JatinderMann> If the focus outline is not on the screen, then
   scroll the focus outline into view by aligning it to the top
   when it receives focus.

   JMann: I'll add a comment to 23978 regarding this note
   ... I will close this but

23980

   [20]https://www.w3.org/Bugs/Public/show_bug.cgi?id=23980

     [21] http://www.w3.org/2014/01/20-html-a11y-minutes.html

   JMann, this one has been fixed, so I will leave a comment and
   close it out.

23981

   [22]https://www.w3.org/Bugs/Public/show_bug.cgi?id=23981

     [22] https://www.w3.org/Bugs/Public/show_bug.cgi?id=23981

   JMann: We agreed to WONTFIX this one
   ... PLH agreed nothing needed to be done

   RS: so lets close this one

   <JatinderMann>
   [23]http://www.w3.org/2014/01/13-html-a11y-minutes.html

     [23] http://www.w3.org/2014/01/13-html-a11y-minutes.html

23982

   Focus Ring out of canvas

   <JatinderMann> The focus ring should not be subject to the
   shadow effects, the global alpha, or the global composition
   operators, but should be subject to the clipping region. (The
   effect of transformations is described above and varies based
   on which path is being used.) When the focus area is clipped by
   the canvas element, only the visual representation of the focus
   area is clipped to the clipping region. The full location of
   the corresponding fallback el[CUT]

   <JatinderMann> When the focus area is clipped by the canvas
   element, only the visual representation of the focus area is
   clipped to the clipping region. The full location of the
   corresponding fallback element is passed to the accessibility
   API.

   JMann: if we change this to focus outline, will that close this
   one?

   -> [25]https://www.w3.org/Bugs/Public/show_bug.cgi?id=24340
   Change reference to the phrases "focus ring" and "focus region"
   to "focus outline"

     [25] https://www.w3.org/Bugs/Public/show_bug.cgi?id=24340

   JMann: transformations will affect focus outlines. If I draw
   one rectangular path doing an hour hand, my focus path will
   continue rotate. Maybe we call it out, maybe not...
   ... I think this needs more work

   RS: agreed

   JMann: Should be a MUST, not a SHOULD requirment

   RS: informing the user could mean calling the AAPI

   JMann: lets keep the change out of the note so its normative

   <richardschwerdtfeger> When informing the user of the of the
   fallback element involves passing the location to a platform
   accessibility api the location is not subject to clipping.

   JMann: i think i agree. We can move the sentence from 3 and put
   it in 4
   ... we want to say inform the user and that the location is not
   subject to clipping
   ... I'll work with Jay to clean this one up a bit
   ... keep the first sentence in step 3 and the second sentence
   in step 4
   ... we'll figure something about the bracket section too

23983

   [26]https://www.w3.org/Bugs/Public/show_bug.cgi?id=23983

     [26] https://www.w3.org/Bugs/Public/show_bug.cgi?id=23983

   Scrolling the focus into view

   JMann: I'll mark this one as assigned. I updated this one with
   the feedback. Still working on it. Just need to add new text

23986

   [27]https://www.w3.org/Bugs/Public/show_bug.cgi?id=23986

     [27] https://www.w3.org/Bugs/Public/show_bug.cgi?id=23986

   Current default path

   <JatinderMann> If the current path has zero subpaths, then
   abort these steps.

   JMann: the first sentence.

   RS: this one is fixed
   ... we can close this one

   JMann: OK, I closed it and left a comment

23987

   [28]https://www.w3.org/Bugs/Public/show_bug.cgi?id=23987

     [28] https://www.w3.org/Bugs/Public/show_bug.cgi?id=23987

   Empty path and drawSystemFocusRing

   JMann: this one is tied to 23986. This one can also be closed.
   ... left a comment and closed.

   JMann: after we make these two more spec changes, I'll
   circulate to the list.
   ... would like to get confirmation from dominic and apple that
   they are happy with the new changes

Testing

   RS: one thing we can do for testing with the clipping one, take
   the test I have checkboxes and make the canvas really small.

   MS: I'll write out all the testable statements so we at least
   know what needs to be tested.

   MS: I can take a stab at writing some tests.

Next Meeting

   RS: lets stay in touch to see what comes out of the TF meeting
   and any emails circulated to implementers to see if we need to
   have a meeting next week.
