When holding an atlas in each hand both hands render the main-hand atlas

[bwanders]

Describe the bug When holding an atlas and the off-hand, and another one in the main hand both atlases render the information from the one in the main hand.

To Reproduce Steps to reproduce the behavior:

1. Take two empty atlases
2. Open the first one, and walk around a bit to fill it out
3. Open the second one, and add a marker on it
4. Put one of them in off-hand, the other in main hand
5. See both atlases display the same thing, check marker just added in only one appear on both or neither. (You can even swap them with f and see both display the other atlases' info)

Expected behavior Both atlases display their own information.
