Description

DatePicker and TimePicker opened unexpectedly when navigating back to previous page on Android API 21 and 23.

Execute attached sample on Android 21 or 23 to trigger the issues. This doesn't seem to affect more recent Android versions (tested on API 30).

Steps to Reproduce

Steps to reproduce

1. Create a new .NET MAUI app (6.0.312 or 6.0.400)
2. Add a button on MainPage to navigate forward
3. Add a page (i.e. SecondPage) with DatePicker or TimePicker, and a button to navigate forward.
4. Add another page (i.e. ThirdPage)
5. Wire up the navigation from MainPage to SecondPage and then ThirdPage
6. Run the app on Android API 21 or 23 emulators
7. After app started, navigate from MainPage to SecondPage, and then ThirdPage.
8. Navigate backwards from ThirdPage to SecondPage, and observe the bug where the picker dialog opens up unexpectedly.
9. Click Cancel.
10. Navigate backwards again from SecondPage to MainPage, and observe the bug where the picker dialog opens up 3 more times.

Expected outcome
The picker dialog does not open up unexpectedly on back navigation.
