NavigationView overflow its size limit when toggling pane

### Describe the bug

When toggling the NavigationView left pane, it overflows during the animation even when a size limit is set.

### Why is this important?

I am creating a transparent window with a NavigationView, and this broken animation is very disturbing.

### Steps to reproduce the bug

1. Put a `NavigationView` inside a `Border` like this
```xml



```
2. Build and run. Toggle the pane. See it's overflowing outside the red border.

### Additional context

_No response_

Reproduce the issue with a NavigationView inside the provided 1280×720 Border and toggle the left pane while observing the animation. Investigate the NavigationView pane-toggle behavior in the WinUI desktop control implementation. Done means the pane remains within the Border's size limit throughout the animation, including with the reported Windows App SDK version.
