Weird window behaviour with SystemDecorations None and resizing

[AlexanderBlackman]

Describe the bug

No matter whether CanResize is true or false, the top edge allows resizing but the bottom and sides don't.

TL TR Corners only allow vertical resize (and the icon is the vertical one), BL BR corners don't allow resize.

This occurs, no matter the size or content.

To Reproduce

Set a window's ExtendClientAreaToDecorationsHint to True
and SystemDecorations to None

Expected behavior

Standard resize behaviour if CanResize is true.
No resize behavoir if it is false.

Avalonia version

11.1.0

OS

No response

Additional context

TBH, I'd actually appreciate a feature to chose an edge to resize from and/or an option restrict it to horizontal/vertical/proportionate.

I also noticed this issue. Furthermore, when using SystemDecorations=None/Border, the window will lose its minimized animation. IIRC this issue existed after a certain release of Avalonia Nightly

That's actually good to hear, if it didn't have this behaviour before, then its just a bug and not an intrinsic part of how Avaloniia works.

A PR is welcome if anyone figures out how to solve it
