1544733 - [caching] Filtered a11y tree is lost after switching to Inspector tab and back

Status: NEW

(DevTools :: Accessibility Tools, defect, P2)

Description

[Timea Cernea [:tbabos][inactive]]

Attachment: Video of the issue

Affected versions:
Nightly 68.0a1 68.0a1 (2019-04-11) (64-bit) - TRY BUILD - 20190411095057

Affected platform:
Windows 10 - so far

Steps to reproduce:

• Go to https://blog.mozilla.org/
• Open devtools and enabled Accessibility
• Perform a full page contrast audit via the "contrast" button
• After the filtered tree is displayed switch to the Inspector tab
• Switch back to the a11y tab

Expected Result:
The filtered tree should be displayed as before.

Actual Result:
The filtered tree is gone and the "contrast" button is in "active" state.

Notes:
I can reproduce this specifically by switching to the Inspector tab directly or selecting a DOMNode #text button from the text leafs filtered. It is not reproducible with other devtool tabs.

Can be done only by swithcing devtool tabs for the first time. Re-checking the full page color contrast and switching to Inspector and back will work fine.

Additional:

The expanded a11y tree is also affected by this.

STR:
Expand the a11y tree as much as possible, find some badges too and switch to the Inspector tab and back. The a11y tree will be barely expanded.
