Dolske is this filed in the right component?

Comment 2

[Justin Dolske [:Dolske]]

Yes. But the new find UI is still Nightly-only, and this correctly blocks the bug (1291278) for shipping it. So this doesn't need to be tracked, as we're not going to uplift any fix (because it's Nightly-only).

Tested on Windows 11 with all 4 default HCM themes and the search is handled as expected - all content that is not highlighted is readable. Attached are screenshots of the light (Desert) and dark (Night Sky) themes with MDN page.

Note: MDN website was updated recently providing both light and dark themes for its UI. I tested each HCM with both modes with similar results.

The bug appears to be fixed.
