Editor scrolling after each save

[aryehbeitz]

When editing with two panes of the same file, so after one side saves, the other pane scrolls down by a line. Eventually, the view is lost.
To recreate:

1. Set autosave to one second.
2. File -> open folder (then select a folder)
3. open a file. then change the layout to two panes
4. click file -> open folder. open the same folder, open the same file and drag it into the second pane of the first editor
5. make a change on one side, the other side will scroll down by one line
   Thanks!
