Floating Panel: Can we get the dimensions in order to set the content insets on the map view?

[rolson]

Is there a way to get the floating panel's location and size so that we can set the content insets accordingly on the mapView? The floating panel resizes and changes location based on device size and orientation. But choosing something like zooming to a feature will not zoom to the right location:

In the image above, zooming to the trace results should center the results in the un-obscured part of the mapview. That could happen if we had a way to get the dimensions of the floating panel.
