"XAML bindings are not updating on property changed events"

Please provide a reproduction case.

Adding a comment to this bug rather than raising another, because it may be the same issue..

Specifically my xaml bindings are not responding to property changed events if the changes are to a subproperty

For example:

Text="{Binding Test}" is fine.. and changes to the property Test update the UI

Text="{Binding SomeProperty.Test}" binds the initial value, but doesn't stay up to date with the changes to SomeProperty.Test

SomeProperty contains an instance of a class which implements INotifyPropertyChanged and the event is firing, with the correct property name.

I have also tried BindingContext="{Binding SomeProperty}" Text="{Binding Test" and this works the same as the other way (initial value set, but not updating)

closing as:
- this is tested and is supposed to work
- reporter failed to provide a reproduction in a year
