Issue: When an AvaPlot element is focused for the second time, Avalonia crashes with the following message:

InvalidOperationException: The control Border already has a visual parent AdornerLayer while trying to add it as a child of AdornerLayer.

ScottPlot Version: 5.0.56

Code Sample:

Simply take one of the Avalonia examples, e.g. Avalonia MultiThreading and hit the tab key repeatedly. When AvaPlot loses focus, the focus adorner doesn't disappear. When it should be focused again, Avalonia crashes.
