Context menu disappears in the Wayland session

In Plasma Wayland, right clicking an icon in the Latte task widget causes the context menu for the task to open briefly before quickly disappearing. Clicking again on the same icon does not show the context menu; I am not in the session to test at the moment, but I believe the reason is that ordinarily a second right click closes the context menu. Clicking again on the same task icon brings up the context menu, and finally it does not disappear. The consequence of this bug is that, at least in the task area widget (the only one I have tested), three clicks on an application icon are required to have the context menu open without immediately disappearing.

This has been tested in Arch Linux.
