What happened?

In our Xamarin Forms app we have an EntryControl whose text property is bidirektional bound to a XF property which in turn is bidirektional bound to a RealmObject property.
When the XF property is changed twice very quickly (by user interaction) the app hangs forever. The XF binding mechanism keeps changing the property value back and forth between the two values.
The issue only occurs when binding to a persistent Realm property! When binding to a transient/ignored property (using RaisePropertyChanged), the binding works as intended.

Please see the attached sample app:

• Press the „Change transient value“ button -> the Entry displays „1“ very shortly and then switches to „2“ as intended
• Press the „Change persistent value“ button -> the app hangs forever

I think there is something wrong with the PropertyChange event propagation of persistent Realm properties.
The following stacktrace was captured, when the MainPage „Value“ property was changed from „1“ to „2“.
There you can see that the WovenSetterMethodInfo actually receives the value „2“ and invokes „RaisePropertyChanged“ - but MyRealmObject.Value is still „1“?! The value should be changed to „2“ before invoking „RaisePropertyChanged“.

Repro steps

Please see the attached sample app:

• Press the „Change transient value“ button -> the Entry displays „1“ very shortly and then switches to „2“ as intended
• Press the „Change persistent value“ button -> the app hangs forever
