In a Wayland session, when a right-click menu is opened, a subsequent left-click somewere else doesn't close it. This applies to all desktop elements: wallpaper, panels, etc. The menu can be closed with another right-click or by left-clicking an item in the menu. The menu also closes if the left-click happens in some other window (e.g. dolphin) and not on a plasma desktop element. Steps to reproduce: 1) right-click on the desktop 2) left-click on the desktop (previously opened menu doesn't close as it should)
