editor: Fix scrolling drag interrupted on gutter hovering (#28924)

Closes #27188

This PR fixes the issue where, when you drag the scroll handle of the
editor and your mouse hovers over the gutter of the next editor,
scrolling stops. I found no good reason to stop propagation on gutter
hover.

Release Notes:

- Fixed an issue where editor scrolling would stop when the mouse
hovered over another editor's gutter.
