[Windows] Unable to adjust the window background color visible when navigating

### Description

I would like my application to strictly adhere to my apps color scheme.
There seems to be one part that I do not have control over and it bothers me.
On Windows, there is a seemingly dark purple plain 'background' which is shown for a few milliseconds when navigating from one page to the other.

This problem is visible when you create a new MAUI project (with content)when you navigate from screen A to B.

### Steps to Reproduce

- creat new maui app
- record screen, so you can play back slowly what happens
- navigate from one page to the other
- see a different color 'background' for a few milliseconds.

### Relevant log output

```shell

Start by creating a new MAUI app with content on Windows, record navigation from screen A to B, and inspect the transient background color during playback. Done means the navigation transition no longer shows an uncontrolled dark purple background and instead follows the application's color scheme.
