Description:
Windows of all LibreOffice program could be resized to 1x1 px. That could be a major issue for an inexperienced user.
Issue is the most noticeable on KDE Plasma but one way or another could be reproduced on Mate, GNOME and Windows. Workaround for KDE Plasma is to set window rule forcing minimum size for a LibreOffice windows.



Steps to Reproduce:
1.Switch to "Tabbed Compact" UI variant
2.Disable "Menubar" with a button on a panel
3.Resize window

First 2 steps are optional (it's just more obvious without menu bar)

Actual Results:
Window resizes to the tiny size.

Expected Results:
Window resizes until it reaches some reasonable limit (e.g. 256x256)


Reproducible: Always
