[Totto16]

Pull Request Template

Description

This was really straight forward fix, just handle the right click correctly and don't propagate the event, if its handled, also don't call the super class handler, since that might to other things, that are not intentional (that was the source of the bug, since the super event handler toggles the class on clicks)

Tested locally and it now works as intended 😄

Fixes #283
