Selection not working correctly on WPF

[Danielku15]

Your environment

• Version used: develop
• Platform used: C#
• Rendering engine used: Skia
• Operating System and version (desktop or mobile): Desktop
• Link to your project:

Expected Results

When you try to select a range of bars in the WPF control the right range should be selected.

Observed Results

Sometimes the UI does not react and sometimes a different range is selected

Steps to Reproduce (for bugs)

1. Setup a WPF project with alphaTab
2. Try to select some bars

Possible Solution

I fear the relative cursor position is calculated wrong in the WPF UI facade.
