Beta/Release Uplift Approval Request

• User impact if declined: When using the accessibility panel, users will see the empty/white badges in the tree for selected rows when the mouse is pressed over the accessibility tree area. This makes the badges look broken.
• Is this code covered by automated tests?: No
• Has the fix been verified in Nightly?: Yes
• Needs manual test from QE?: No
• If yes, steps to reproduce:
• List of other uplifts needed: Bug 1559317
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): This was a regression from bug 1558188, dealing with focus and styling for accessibility tree in accessibility panel. Should not be risky as it's just a CSS style to not white out the badges.
• String changes made/needed: None
