Clone Xamarin.Forms to c1fbfae03
Use VS to build Xamarin.Forms in Visual Studio; We know env setup can be a pain (installing all the SDKs etc) so feel free to reach out for support; we promise open other issues to make it worth your while. :)
Run create-nuget.bat to create a private nuget package
Open reproduction in https://bugzilla.xamarin.com/show_bug.cgi?id=56030
Install the private nuget package
Set a breakpoint at https://github.com/xamarin/Xamarin.Forms/blob/c1fbfae03ca04dd70a31a00042c745658cc8bd97/Xamarin.Forms.Platform.Android/FastRenderers/LabelRenderer.cs#L215 which should be just at the top of UpdoateColor()
Run the reproduction and see that the breakpoint is hit
Note that the top of the stack is `VisualElementPackager..ctor` but I'm expecting `UpdateColor`

We found a probable root cause for this. I'm assigning to Dean, who was working on that. Dean, feel free to kick it back to me if appropriate.
I suspect this is related to recent issues with debugging. Its possible that old debug symbols are being picked up.
the latest being xamarin-android/master/71511791.
We'd need to re-test on a XVS build which includes that commit.
I am going to mark this as fixed for now since one of those commits is probably responsible for this issue.
