User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.157 Safari/537.36 Steps to reproduce: Within a dynamic web application, attempt to utilize an aria-live region to announce either status information. * Aria-live region populated by using javascript to append child elements to the live region * Assertiveness set to polite (although issue also applies to other settings) Mac 10.10.5, Voiceover and Firefox 40.0 Actual results: Voiceover reads nothing from the aria-live region. Expected results: When a new child node is appended to the aria live region, the screenreader should announce the text value of that node. Note that Windows 7/Firefox 40.0.2/JAWS 16 works as expected.

Known issue that has to do with our as of yet incomplete implementation of Mac accessibility APIs.

Status: UNCONFIRMED → NEW
Ever confirmed: true
Is this bug still valid/reproducible?
Flags: needinfo?(mzehe)
Very likely yes. We haven't done any work on Mac a11y in recent months due to resourcing/prioritization, and thus haven't actively pursued this or other Mac-related bugs.
Flags: needinfo?(mzehe)

Verified today, still an issue.

VoiceOver pre-caches live region data and does its own deltas to
know what to parts of a subtree changed, and what to announce
based on AXARIAAtomic and AXARIARelevant.

I added a removed event as well. This will help us cache a "live region"
flag in the main process and avoid sync round trips for attributes when not needed.

We use an ivar boolean flag to cache the existance of a live region. This lets us
hide the live region AX attributes and avoid sync round trips to content.

Depends on D96291

I think VoiceOver uses this to pull in all live regions so it
can check for deletions when they change later on.

Depends on D96292

VoiceOver seems to do all the heavy lifting of figuring out what portion of the
live region should be read.

Depends on D96293

Ah sorry. Added an include, and tested on try. I think we're good:
