Description:
Environment: Fedora 35 KDE Plasma Spin (on X11, not Wayland)

Problem: Hovering and interacting with the toolbar results in no keystrokes being handled any more by Libreoffice. 
I can reproduce this behavior in seconds, when I want to ue the "Set Paragraph Style" dropdown and accidentally open the tooltip of the button right to it (Update Selected Style). After changing the style of the paragraph, the keyboard is just disconnected from LibreOffice. I cannot edit the document any more, even CTRL+S isn't working any more. However, the mouse is still good, I can use the whole menu and toolbar, I can even select text and change the style, but keystrokes are just being ignored.
When this happens I have to close writer and open the document again.

The problem appeared around the beginning of january 2022. Since Fedora is quite current on released versions, it should be related to a more recent patch release.

Steps to Reproduce:
1. select a paragraph
2. use the mouse to change the paragraph style using the drop down
3. hover a little bit around and then open the drop down. When it will open not earlier as on the second click, you probably reproduced the issue
