ScrollViewer hangs when click + scrolling until window focus is lost

[EvilAngel00]

Describe the bug

When using the ScrollViewer control, attempting to scroll while pressing down a mouse button (left, right or middle) will freeze the application window until focus is lost by either clicking on the title bar, resizing or minimizing the window.

Steps to reproduce the bug

Minimal repro project:
TestScrollViewer.zip

1. Open the application
2. Scrolling with mouse wheel should work normally
3. Press a mouse button and while the button is pressed, attempt to scroll
4. The ScrollViewer freezes and it's not possible to click any of the buttons anymore

Expected behavior

The ScrollViewer should still be able to scroll while mouse buttons are pressed.
