Steps to reproduce:

1. Open the attached project
2. Open the Audio Mixer window
3. Resize the window so the item list receives a scrollbar
4. Scroll the window using the mouse scroll wheel (the window scrolls as expected)
5. Press the + button to add a new group
6. Try scrolling the window using the mouse wheel again

Actual results: The window does not scroll using the mouse wheel when an item is being named

Expected results: The window can be scrolled using the mouse wheel when items are being named

Reproducible with versions: 6000.0.79f1, 6000.3.20f1, 6000.5.4f1, 6000.6.0b5, 6000.7.0a3
