Description

When using an Entry control in a page with a Binding to an ObservableProperty of type string in a ViewModel, updating its Text content from that ViewModel works. After editing the Entry in the app (using the keyboard), the entry seems to stop "listening" to the ObservableProperty - its Text value cannot be set anymore from the ViewModel. To demontrate this see the animation below, where we added three Entries to show the effect: all Entries update each other via the Binding and the Button, but as soon as some text is entered manually in an entry, it no longer updates via the Binding.

Steps to Reproduce

1. Create an empty .NET MAUI project
2. Add one or more Entry controls to a page (e.g. the MainPage)
3. Bind their Text to a property of the MainPage's ViewModel
4. Add a button to that Page
5. Let that button update the value of the Binding
6. Run the app
7. Click the button (and see that it works)
8. Edit the text of one of the Entry controls
9. Click the button again and see that the text of the edited Entry no longer updates
