Rounded corners for main window are visible when script editor is popped out (see screenshot)

[CZakarya]

Tested versions

v4.3.stable.flathub [77dcf97]

System information

Vanilla OS Orchid (based on Debian Sid)

Issue description

When the code editor is popped out into it's own window, the UI still has rounded corners on the edges. Theme set to light and rounded corners set to 6 for maximum visibility

Steps to reproduce

Open the script editor and pop it into it's own window. It is very hard to see with the default theme settings (it is visible, I checked), but for better visibility try setting the editor theme to light and rounded corners to the highest value (I found it to be 6).

Minimal reproduction project (MRP)

As far as I can tell, this issue is not dependent on the project. I have tested this with two different projects, one 2D and one 3D (I don't expect that to make a difference).
