when Imagemagick is closed stay displayed in the dock

[J-Paul BERARD]

When using ImageMagick (with a Wayland session) and you close it, the icon stay in the dock with an indicator (despite it's closed).
The task doesn't exist anymore in the task manager.
If you click again on this icon in the dock, a context menu appears at the top left of the screen but this menu is not active : you can do nothing with it
It is impossible to launch again the app until you close the session

Same kind of bug than 1932328 with Thunderbird, but different app : Wayland problem

Ubuntu 21.10 desktop, Wayland, AMD Fx, but it was the same with 21.04
