Description of problem: In firefox-wayland, the placement of the pop-ups is very odd. In menus like the browser history, it is drawn partially outside of the screen, making impossible to browse through its sub-menus. Other pop-ups appear far away where they should, for example when clicking in the green lock of a https web site. I think this issue is worsened when using a multi-monitor setup. Version-Release number of selected component (if applicable): firefox-wayland-65.0-2.fc29.x86_64
This issue is tracked upstream already.
