Several ibus menus open at the same time. Even though I clicked into Konsole which can be seen because of the menu from konsole.
I installed Fedora-Workstation-Live-x86_64-34-20210308.n.0.iso in Japanese in kvm.
Installed plasma desktop using dnf.
Logged into plasma (Wayland)
Ran 'im-chooser' and selected ibus as the input method.
Added ibus-anthy and ibus-typing-booster as input methods using 'ibus-setup'.
Tried to use the input methods.
When clicking with the left and the right mouse button on the ibus-icon in the plasma panel, menus pop up, one menu for left click and one menu for right click.
It is possible ot have several of these menus open at the same time.
The behaviour is quite strange.
When clicking in a window like 'Konsole', these input method menus should close, but often they don't.
See attached screenshot.
In the screenshot you can see two menus opened with left click at the same time, in one of them (the left one) ibus-typing-booster is selected, you see the special menu entries for ibus-typing-booster at the top. At the right side you see a menu opened with left click which shows the special menus of ibus-anthy at the top.
Below, (invisible), there are several more of these menus including one opened by right click.
