Keep menu panels above the selected-marker tooltip#6125
Merged
Conversation
When a marker stayed selected, its sticky tooltip rendered on top of the Re-upload and other top-bar menu panels, covering them and intercepting clicks. The panels already carry a higher z-index than tooltips (--z-arrow-panel above --z-tooltip), but .profileViewer set z-index: 0, creating a stacking context that trapped the panels at its own altitude. Tooltips render in the body-level #root-overlay layer, which paints later, so they always won regardless of the scale. Removing that z-index lets the panels and tooltips share the root stacking context, where the scale orders them correctly. Closes firefox-devtools#6102

Closes #6102.
I've inspected the UI visually and it seems like there is no regression to me but please have another look yourself too.
