Description:
On my Mac mini - but not on my MacBook Air - several dialog boxes are always displayed in maximum size and opens an additional tab page instead of being displayed on top of the main window. It is possible to decrease the size by dragging the title bar of the tab to the main window and by double clicking on it.However, this is not quite comfortable.

Steps to Reproduce:
1.Open menu "LibreOffice"
2.Click on "Settings" (in German "Einstellungen")
3.Dialog window appears as 2nd tab in maximum size

Actual Results:  
1.Open menu "LibreOffice"
2.Click on "Settings" (in German "Einstellungen")


Expected Results:
3.Dialog window appears as 2nd tab in maximum size

I would expect a dialog box on top of the main page and not that a 2nd tab is opened.


Reproducible: Always


User Profile Reset: No
