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

<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

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.
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

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

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
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
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
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.
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.
