Question
Illustrator hangs indefinitely when dragging the scrollbar thumb
Steps to reproduce:
1. Create a new empty document.
2. Open the Layers tool window.
3. Create several new empty layers, enough for the vertical scrollbar to appear.
4. With the left mouse button, begin dragging the thumb of the scrollbar (the dark gray verticall pill).
5. Illustrator stops responding indefinitely.
This happens in Illustrator 28.5 running on macOS 14.5
