Are you sure this is due to backdrop-filter? I see it being none here, it seems only used in High Contrast Mode...

In order to honor Highlight/HighlightText colors, we reimplemented the text selection in using a backdrop-filter (a div with a clip-path has a SVG backdrop filter). It's a real improvement when selecting in HCM and it's a way better too in non-HCM because we've a pretty good contrast now.
