@jessegreenberg is this what you would expect to see when going "line by line" or is it a bug on our side?

zepumph commented 2 years ago

I see that the content that was skipped is all the dynamic content, which is nested in a div.

p -heard when reading line by line div - not heard p - heard

This seems like a voice over bug to me, we should test this as a p and see if it remains. Perhaps we will report to apple.

Also I should see if it works on page load vs after changing some dynamic stuff (forcing a redraw)

@jessegreenberg noted that this has occurred before, in https://github.com/phetsims/john-travoltage/issues/449

I tried to get to the bottom of this in https://github.com/phetsims/a11y-research/issues/175 but did not succeed. I don't see anything in the PDOM that should be causing this. But I was not able to produce the bug outside of a PhET sim so it may be a problem with our infrastructure. But I feel like I have exhausted everything we can try.

I would recommend we add this to the list of known AT issues and not let this block publication.

The problem was identified in https://github.com/phetsims/a11y-research/issues/175 and we decided not to apply a workaround. A bug report will be submitted to Apple and this has been added to the list of known AT problems.

This no longer blocks publications but I'll let @zepumph close up in cae there is anything else.

Agreed! Thanks for investigating.
