NavigationView Pane Toggle Button Misaligned When Expanded and IsBackButtonVisible="Collapsed"

[NotYoojun]

Describe the bug

When the NavigationView is in expanded mode and IsBackButtonVisible is set to Collapsed, the pane toggle button is not vertically centered relative to the NavigationView header area.

The alignment is correct in other states, so this appears to be a layout/styling bug.

Discussed in #333 with @66BA9Q-ME49

I'm talking of the pane toggle button. As you can see in the screenshot below, the pane toggle button of the WPF app is not centered to the NavigationView. In comparison, button of the WinUI3 app is properly centered.
