Comment 0 for bug 1618405

Exactly like bug #552920 but for Lockscreen and Integrated menus:

1. Click on the volume control to open the sound menu.
2. Move the pointer diagonally to click on the maximum volume button.

What often happens: The sound menu closes, and the menu next to it opens.

Example in an informal usability test: <>

What should happen: The sound menu stays open.
