Description eam74 2017-02-02 16:46:38 UTC 
This is probably a minor bug but really disruptive. I'm trying to refactor a big file, so I cloned the view and have it open in two tabs. I have the file scrolled to a different location in each window (e.g. the old function, my new function).

To reproduce:

1. Clone a document view (call them View A and View B)
2. Place cursor in different locations in each view
3. Make a change in View A, then undo
4. Observe position of cursor in View A and View B

Expected: Cursor in View A moved to where the change happened. The cursor in View B is unaffected.

Actual: Both cursors have moved. If the document was large enough to scroll, the scroll view also jumps in View B such that the cursor is visible.
