TextEdit is blocking Shift + scroll when hovering over it

Issue description

Seems like variation of #29201

When you Shift+scroll in a big ScrollContainer and you hover mouse over TextEdit, it will block your scroll even if it doesn't have horizontal scrollbar.

Steps to reproduce

1. Add a Control and create a Theme
2. In the Theme editor, use Shift + scroll to scroll
3. Now hover mouse over TextEdit, try Shift + scrolling and compare the result

Minimal reproduction project

No response

EDIT:
Also worth to mention that it only blocks scroll to the right (i.e. mouse wheel down).

Still valid in dc7235b
It's a bit better though, because it works randomly lol

Notice the choppy movement when I scroll right.
