Description:
I am assuming this is everywhere where tabs are used in dialogs and not limited to this specific location.

Version: 5.4.0.0.alpha0+

Locale: de-DE (de_DE.UTF-8); Calc: group

Steps to Reproduce:
1. Start LibreOffice, open a Writer document.
2. Tools > Macros > Organize Macros > LibreOffice Basic
3. Click on the Organizer... button
4. switch between the top three tabs

Actual Results:  
Note that the rounded corners of the tabs at the very left and right of "Modules | Dialogs | Libraries" are rounded. But when switching tabs, the rounded corners wander around and the very left which should be rounded no longer is.

See screencast to get an idea.

Expected Results:
Tabs should be rounded on the outside and straight seperators on the inside. And that should not switch.


Reproducible: Always
