WinUI: Popup shows underneath AutoSuggestBox results flyout

[eshalisa]

Describe the bug

Get test project from https://github.com/eshalisa/TestProjects
I have a popup that should show over the AutoSuggestBox results flyout when I hover. It is always showing underneath, even when it opens after the results flyout.

This worked on Microsoft.WindowsAppSDK version 1.3.230724000.

Steps to reproduce the bug

Launch test app
Type "A" into the AutoSuggestBox
Put the curser over the "Apple" result

Expected behavior

The popup should show above the flyout if it opens after the flyout.

Try setting ShouldConstrainToRootBounds=false on the Popup.
