NVDA not reporting expanded when collapsed link on website is pressed and changes state

You have arrived at a default issue template (bug report).
It is preferable to choose the type of issue to submit.
Hint: Swap to the preview tab to be able to click the links.
Direct links to the templates:

• Bug report
• Feature request

Steps to reproduce:

• Go to http://catalog.ulm.edu/content.php?catoid=31&navoid=3902.
• Navigate to the ACCT 1010 - Accounting Survey collapsed link.
• Press Enter.

Actual behavior:

Firefox: NVDA stays quiet and the section gets expanded revealing new content.
Edge: NVDA repeats the title of the link (ACCT 1010 - Accounting Survey in this example) and the section gets expanded revealing new content.

Expected behavior:

NVDA should report "expanded" while the browser does its thing of expanding the section and revealing additional content. This behaviour should be consistent across different web browsers.

ccc @jcsteh for the Firefox part.

This is a website authoring error. Rather than changing the expanded state on the link, the page removes the link from the document and replaces it with a new one. As far as screen readers are concerned, it is an entirely different link.

I'm not sure why the name gets read in Chromium.

Aside from this being fixed by the author, the only way to work around this in NVDA would be #8869, which got reverted some time ago. Even then, it would report the whole link, not just "expanded".

This is fixed in Firefox and works as expected in NVDA 2023.1 RC1 and Firefox 111. Closing as works for me.
