Status: RESOLVED DUPLICATE of bug 1702847

(Firefox :: Menus, defect)

@ Gijs, I believe this is a regression from your fix for dark mode selector bug 1702626. I bisected this regression to this pushlog with bug 1702626:

https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=78fcad0bb24fa5188c3d1d85b3e8f30d0df13eeb&tochange=e2b5a90e8f259cd638f79efb191d3fba550f3b73

Steps to reproduce

1. Set browser.proton.contextmenus.enabled pref = true and restart Nightly. (The browser.proton.enabled pref can be true or false; it doesn't matter for reproducing this bug.)
2. Change your Firefox theme to Mozilla's "Dark" theme.
3. Load a Bugzilla bug page, such as this one.
4. Click to open a drop-down menu, such as the "Priority" menu.

Expected result

The drop-down menu items should be readable. I don't know if Proton dark mode specifies whether the menu items' background color should be white or black.

Actual result

The drop-down menu items are all black (text on black background?), except the menu item highlighted by your mouse pointer. See the attached screenshot.

Hah! interestingly I think this is bug 1702847, which I just filed and sent a fix + test for.
