That issue got auto-closed for no feedback. Looks like now it's being tracked in https://github.com/microsoft/microsoft-ui-xaml/issues/3108.

So far no rationale from Microsoft. They don't seem interested, maybe need a pull request. If we fix it in ModernWpf, would a WinUI fix be identical?

Thank you. I think that's confusing because section spacing is not GroupBox's job. It's a job for things like `SimpleStackPanel.Spacing`. GroupBox leaves an unwanted gap after the last section, or...

Using `InvalidateMeasure` instead of `InvalidateVisual` gets rid of the extra space in the workaround. I have to call it from BeginInvoke to make it work for [ModernWpf.SampleApp][1], for some reason:...
