Whole App Shell and Shell content disapear when changing between tabs fast enough (Release mode on Android)

[MauiUIui]

Description

When changing between two different tabs quickly back and forth (or better repeatedly tabbing simultaneously) there are times when the app shell completely disappears and the only thing that remains from the app to be seen would be the tab bar. This is a state that the app doesn't recover from on its own. Now if one tabs on one of the tabs, nothing would happen (probably indicates that this is the one actually active). However tabbing the second one would change to it and make everything appear correctly again.

First	Second	Third

Steps to Reproduce

1. Create a Maui App.
2. Create at least two ContentPages with different background colours for clarity.
3. Add a Tabbar which includes two ShellContents who's ContentTemplates are the above mentioned ContentPages.
4. Give the ShellContents Titles
5. Start in release mode (provides the necessary speed I guess).
6. Repeatedly tab simultaneously on both tabs.
7. You should notice the white page and the disappearing of the whole shell.

The tricky part is really is to stop tabbing when it appears. I only achieved that by repeatedly tabbing both tabs at the same time and stopping randomly.

This issue is easier to reproduce and watch on physical devices than emulators
