Steps to reproduce: 1. Launch multiple apps. 2. Click on one app after another with right click. Similar steps can be done also in Task Manager - for example - by right clicking on one app after another in Favorites list. Actual result: Multiple right click context menus appeared in Task Manager. Expected result: Single right click context menu appear for each right clicked app - previous context menu disappears.

I can reproduce this. Furthermore, with a multiscreen setup, I can open a plasma context menu (right-click on the background-image) per screen at the same time. Additionaly: Plasma context menus close when I click anywhere (doesn't matter if it's another application or the plasma itself). This is intended behavior, however, this does not work for context menus opened by right-clicking on panels. The only possible way to close a context-menu opened by right-clicking a panel is by right clicking on the panel again. (Which should probably actually open a new context-menu replacing the old one?). Not even left-clicking on the panel closes it.
