I had an epiphany where the odd behavior comes from: It was caused by my custom UI scaling factor of 172% (=165 DPI). Setting it to 150% (144 DPI), a value suggested by Windows, gives the expected window size.

I still think the patch is a good idea because it makes the test more robust against such configurations. I’ll resend it tomorrow with an updated title and description.
