Additional context
Seems like it was introduced in: #2621. Notably this line:

egui/crates/egui/src/menu.rs

Line 446 in ce67d73

&ui.style().visuals.widgets.open

[lictex]

its a dark style issue, works fine under light mode..

dark open style is wrongly set to be same as noninteractive, and should use hovered values instead

egui/crates/egui/src/style.rs

Lines 869 to 870 in 1581f02

	open: WidgetVisuals {
	weak_bg_fill: Color32::from_gray(27),
