We're seeing this as well, Android only but with a slightly different callstack:

JniPeerMembers.AssertSelf (Java.Interop.IJavaPeerable self)
JniPeerMembers+JniInstanceMethods.InvokeNonvirtualObjectMethod (System.String encodedMember, Java.Interop.IJavaPeerable self, Java.Interop.JniArgumentValue* parameters)
View.get_Context ()
NativeGestureRecognizer.ToDip (System.Single px)
GestureListener.OnLongPress (Android.Views.MotionEvent e)
GestureDetector+IOnGestureListenerInvoker.n_OnLongPress_Landroid_view_MotionEvent_ (System.IntPtr jnienv, System.IntPtr native__this, System.IntPtr native_e)
(wrapper dynamic-method) Android.Runtime.DynamicMethodNameCounter.153(intptr,intptr,intptr)
