I'm wondering if this is actually a bug or excepted behaviour on iOS. Let's make a discussion about it.
When you are focusing an entry, and trying to close it by tapping on the NavigationBar's free space, the entry does not get unfocused and the virtual keyboard keeps presented.
Steps to Reproduce
Create a Shell with content
Place a SearchBar/Entry on content page
Run the app.
Click in the search bar
Try closing it by tapping on the navigation bar
Expected Behavior
I assume it should close the virtual keyboard and trigger the unfocus event.
Actual Behavior
The opposite how it should work :P
Basic Information
Version with issue: Xamarin.Forms 5.0.0.2401 // Probably MAUI is affected too

Create an event subscriber for the TextChanged event, and when the text is string.isnullorempty, trigger the usercontrol's UnFocus method manually.
