Editing a panel in the 2nd column of a 2 column dashboard causes it to duplicate to the first column.
This may be related to T10145, though the steps to produce the outcome are different. Feel free to merge them if you feel this is the same problem.

- Create a new empty dashboard, 2 columns 2/3 1/3
- Add W1 and W2 to left column, W3 and W4 to right column
- Edit W3 and save your changes.
W3 is then duplicated and added to the end of the first column, while also remaining as the first panel in column 2.
If you delete the panel in the first column, it is removed from both columns. (Is this a separate bug? Should I file that? I don't know if you are supposed to be able to add a nav panel multiple times or not, say for putting NAV above and bellow a large panel).
