[BUG] [Regions] [FlyoutPage] View discovery on FlyoutPage

[lucacivale]

Description

View discovery inside a FlyoutPage doens't add any view if the fylout details page doesn't contain a region too.
If the details page contains a region the flyout views will be discovered and added also. I would expect that all associated views are displayed even if the details page doen't contain a region.

Steps to Reproduce

Run the project with and without RegionA on PageA

PrismRegionsFlyout.zip

Platform with bug

.NET MAUI

Affected platforms

Android, I was not able test on other platforms

Did you find any workaround?
