ExtendClientAreaToDecorationsHint=True, ClientArea gets shifted to the left.

[cyraid]

Describe the bug
When the ExtendClientAreaToDecorationsHint is set to True, it seems the Client Area gets shifted over to the left by a tiny bit. This is shown in the screenshots (I made a border white so you can see it clearer).

To Reproduce
Set ExtendClientAreaToDecorationsHint to True

Expected behavior
The client area not to get shifted to the left (probably by the amount it saved by extending?)

Extend to Decorations False:

Sorry about the noise in the emails about reopening the other issue, I'll put it here.
Might be triggered by the same bug I don't know, but when using CompositionCustomVisualHandler and Skia, the Canvas is always offset up by the title bar size. This can be seen by enabling ExtendClientAreaToDecorationsHint to True and ExtendClientAreaChromeHints to NoChrome which the Canvas client area will start drawing at 0,0 (from it's UserControl) which it's supposed to.

Edit: After more testing without CanResize, it's mostly the left that's being thrown off after more testing. The Y seems to be okay.

Also seems to happen when CanResize is True and when the window is maximized.

@maxkatz6 I'm no longer using CompositionCustomVisualHandler and the problem still persists. It might seem like a small issue, but having everything offset when maximized means I have to have separate styles when [WindowState=Maximized] to correct those issues.
