Mathml is not read as math in live regions #7485

Open derekriemer opened 7 years ago

derekriemer commented 7 years ago

Filed on behalf of @benetech

Steps to reproduce:

  1. go run this example page.
  2. Wait ten seconds, then ten more seconds.

Expected behavior:

NVDA should read the math in the live region.

Actual behavior:

NVDA reads only the text of the live region, as if math doesn't exist.

System configuration:

NVDA version: Doesn't matter

NVDA Installed or portable: installed or Portible.

Other information: With any browser, and mathplayer.

Windows version: Windows 10 Version 1607 Build 14393.1066

Name and version of other software in use when reproducing the issue: mathplayer.

Technical:

This codepath for live regions is not capable of handling this usecase. The code simply gets text with no formatting from the browser.

@derekriemer, it appears the link that you provided no longer exists. Do you have another use case?

derekriemer commented 7 years ago

usecase exists now.

I am unable to reproduce the reported issue with the provided test case. Every ten or so seconds, NVDA automatically reports something, and a quick snippet of Speech Viewer contents when the page is opened is as follows: "lorem ibsum The power of x 1 2 is x to the powr of one over two.
The fraction of x 2 is x devided by two.
The power of x 1 2 is x to the powr of one over two. " Isn't the above speech expected behaviour, or am I missing something? @derekriemer

No, this isn't real math. x2, not the fraction (Read that with mathplayer).

Thought I'd link this up with a relevant conversation elsewhere:

https://github.com/w3c/aria-practices/issues/696

Seems like there's interest in making this happen.

Adriani90 commented 5 years ago

So I am understanding correctly that this one needs and external fix?

pbblair commented 5 years ago

External fix seems ideal, but would require more specific guidance for browsers on how to handle MathML within accessible names.

I wonder, since MathML is being read correctly elsewhere by NVDA/MathPlayer, is it feasible to ignore the browser's computed Accessible Name when math children are present?
