P: Masking Effect list scrolling not working with mouse scroll wheel under Windows

Issue: 
When scrolling through list of masking effects, mouse scroll wheel does not work under Windows (it works under MacOS).

• Lightroom Classic Version Number: 
  Adobe Photoshop Lightroom Classic Vesion 11.2 with Camera Raw 14.2
  
• OS Version Number: Windows 11 Pro, Version 21H2, Build 22000.556

Steps to reproduce:

1. Open Lightroom Classic
2. Select a picture
3. In Develop mode, click on Masking symbol
4. Click on Effect field
5. Use mouse scroll wheel to scroll through a longer list of effects

Expected result: list should scroll
Actual result: list does not scroll. It only scrolls, when I click with the left mouse button on the arrow button bottom left or top left of the list.
