Uno: TappedRoutedEventArgs.GetPosition throws a 'Specified method is not supported' exception in WASM

[ibebbs]

Current behavior

TappedRoutedEventArgs.GetPosition throws a 'Specified method is not supported' exception when a 'relativeTo' parameter is specified.

Expected behavior

The correct position is returned with no exception thrown.

How to reproduce it (as minimally and precisely as possible)

c# private void TappedEventHandler(object sender, TappedRoutedEventArgs args) { try { var position = args.GetPosition(args.OriginalSource as UIElement); coordinates.Text = $"Clicked: {position.X}, {position.Y}"; } catch (Exception e) { coordinates.Text = $"Exception while calling TappedRoutedEventArgs: {e.Message}"; } }
