2035185 - [linux][wayland] mouse input on popup menu ends up on the main window instead

Status: RESOLVED DUPLICATE of bug 1984812

(Core :: Widget: Gtk, defect)

Description

[ales.astone]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:149.0) Gecko/20100101 Firefox/149.0

Steps to reproduce:

1. Open a context menu by pressing and holding right click
2. Move the pointer over the popup
3. Left click
4. Finally release the right click

GNOME 50, Firefox 149.0.2 and nightly.
Weirdly, there was a point in time where stable was affected but nightly wasn't.
Today, I can reproduce equally in 149 and nightly

Actual results:

The popup menu items do not get highlighted on pointer hover. Instead, widgets in the top-left region of the main window get highlighted as if they were being hovered.
The left click is eaten by the main window too.

Expected results:

Mouse input is correctly redirected to the popup menu.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Can you use mozregression to find the broken commit?

It's not a regression, reproducible back to 2020-02-01 build with GNOME 50 on Ubuntu 26.04 (mutter 50.1).

Seems like a duplicate of Bug 1984812.
