go_to_line: Fix goto line + mouse click jumps to previous scroll position (#26362)

Closes #20658

Now, when the "Go to Line" palette is open:  
- Clicking on the editor will dismiss the palette without changing the
scroll position. (PR change)
- Pressing Enter will jump to the line number entered in the palette.
(Unchanged)
- Pressing Escape will jump back to the previous cursor location.
(Unchanged)

Release Notes:

- Fixed an issue where clicking the editor with the mouse while the "Go
to Line" palette is open would cause it to jump to the previous scroll
position.
