Search filter toggle buttons have broken UI [regression]

[LilithHafner]

The "Filters" toggle buttons' state is no longer visible in the UI.

After clicking some of the buttons a bunch I got this search result, with no indication of how I can get back to a normal result.

New UI introduced in #2202 cc @Hetarth02. The UI looks fine in the PR demo, but now it seems broken on docs.julialang.org on both IceCat and Chromium.

Does julialang's docs introduce some custom css?

I think it may be due to that. Also, can you confirm if this also happens in the light mode as well or not?

Edit: I think there might have been some changes(cc @mortenpi ) in the css files for dark theme in between. I have confirmed that the filter state indicators are working fine in the light mode.(cc @LilithHafner )

Edit: I have found the issue, hopefully it resolves the bug.

Can confirm it works for me in light mode.

Did a PR which fixes this in dark mode as well.
