Can't see the 'Clear Saved Changelogs' button with a dark theme

[keithx2]

If a dark theme is enabled (about:addons -> Themes -> Dark), then the button is very hard to see.

Huh, that's odd. The button's background color is rgba(12, 12, 13, 0.1). Because it has an opacity of 0.1, it looks like a light grey on a white background but black on a black background. Don't know how I missed that when adding the dark mode.

Not that it matters, but I managed to track down the original source of this quirk. Interestingly, that's the correct default button background color for Photon.
