This investigation cannot be done using mozregression considering it only occurs on the aurora channel. I've performed a manual investigation and I've discovered that the first build it started occurring on was DevEdition v103.0b1.
It appears to ONLY occur on the Dark Theme and not on the Light one.
Also, it was only reproduced on older versions of Mac OS. It reproduces in 10.13.6, but not in 11.6.

Based on comment#1 removing keyword.

Comment 3

Given this WFM on more recent macOS (Monterey, and comment #1 suggest it also works fine on macOS 11), I think this is a widget issue and depends on the theme colours we get from the OS vs the high contrast mode stuff.
