PlotView in ElementHost does not work. #1800
Description
Steps to reproduce
I included a repo as a Zip with this issue, to make it easier to reproduce the issue. Just hit start and you should be able to see that the PlotView is not rendered inside a UserControl, which is contained in a ElementHost-Control. If i execute the same code without the ElementHost inside a WPF-Window-Control, the Plot is appearing just fine.
OxyPlot version: 2.1.0
Platform: WPF
.NET version: .NET Framework 4.7.2
Expected behaviour
I am expecting, that the PlotView is rendered and my plot is shown.
Actual behaviour
The PlotView stays blank.
