Undo can move the cursor away from the change, obscuring what was just undone

[nardog]

Describe the issue

Steps to replicate the issue:

• Start editing something long enough there is a scrollbar
• Scroll to bottom (Ctrl+End)
• Enter something
• Do an undo (Ctrl+Z)
• Scroll to top (Ctrl+Home)
• Do a redo (Ctrl+Y)
• Do an undo (Ctrl+Z)

Actual behavior:
The cursor goes to top (and so does the scroll view), so it's not clear what was just undone.

Expected behavior:
The cursor stays adjacent to the chunk that was changed, so it's clear what was just undone.
