Form.FormBorderStyle == SizeableToolWindow not working.

[IanMarteens]

• .NET Core Version: Preview 6
• Have you experienced this same bug with .NET Framework?: No

Problem description: Setting FormBorderStyle to SizeableToolWindow is not working.

Actual behavior: Same caption bar height as a Sizeable form.

Expected behavior: The caption bar should be narrower, as in .NET Framework.

Minimal repro:: change the property in the main form of a minimal project, change its FormBorderStyle, run and compare.

@IanMarteens I am unable to repro the issue in Preview9.
It is working as expected (left: .NET 4.7.2, right: .NET Core 3.0 P9):

Can you please confirm that you still have the issue?

Still happens in my PC. Don't know if I have to update my desktop preview. I include installed runtimes below the image:

BTW, I'm running this on a FullHD monitor (1920 x 1080) with no text scaling.

What your screenshot is showing is expected and by design due to the change of the DefaultFont (#656).

Ok, thanks.
