[pointerevents] clarify what happens if touch-action is changed dynamically

patrickhlauke has just created a new issue for 
https://github.com/w3c/pointerevents:

== clarify what happens if touch-action is changed dynamically ==
It's probably implicit in the prose for "9.1 The touch-action CSS 
property", but: what should happen if, on `pointerdown`, the 
`touch-action` for the element is changed dynamically (for instance, 
from `auto` to `none`, based on the document's scroll position, for a 
naive pull-to-refresh implementation)? I assume that at that point, 
it's already too late and the user agent determined what to do 
(whether to handle the pointer/gesture or not) based on what 
`touch-action` was the moment when `pointerdown` was fired...if so, 
would it be useful to clarify this in a note?
