Please describe the problem:
In fullscreen, if I click on the sound button to change the volume, it opens a slider and sets the volume to 0 (which is the position where the mouse is).

It doesn't happen when in normal screen (not fullscreen), except when the windows is near the bottom of the screen.

When clicking on the sound button, the event should not be dispatched to the slider component which opens

Steps to reproduce:
1. Play a video with the bottom of totem near the bottom of the screen (or fullscreen)
2. Click on the sound button


Actual results:
The volume changes

Expected results:
Nothing should change

Does this happen every time?
yes
