Bugzilla

Thanks for the report.

This also happens in Microsoft Edge when the Windows high-contrast theme is enabled there, so I think this is, in fact, "High-Contrast Backplates" feature (proposed by & referended from Edge) working-as-expected.  The dark backgrounds behind the controls here are "backplates", and if we didn't draw them, it'd be very hard to see the controls in high-contrast mode, because there's a white-gradient background behind the text.

(The white-gradient is actually a gradient from transparent to `currentColor`, and CNN intends for `currentColor` to be black, but is [and all text] is white in high-contrast mode.  So if we weren't drawing the backplates, we'd end up with white-controls-on-whiteish-background here. This is  the issue that backplates are meant to address.)

Having said that: the backplates are a bit "tighter" in Edge, so they look more reasonable & less like artifacts there. There may be some room for improvement/experimentation on that -- let's morph this bug to be about that.
