Map GUI-Item Frame breaks Map item display

Put the summary of the bug you're having here

What I expected to happen was...:
After mounting the same set of 3 maps on the wall in two different locations (roughly 1000-2000 blocks apart), I should still have been able to view myself(white arrow) on a "player-held" map assigned to toolbar.

What actually happened was...:
Instead, the green arrows indicating "you are here" on the wall mounted maps are appearing on my "player-held" map, and no matter which of the 3 maps i held and viewed as a player, the white marker indicated that i was on a different map, even if i was standing within the borders of the map i was holding in my hand, my white marker still indicated i was off the map.

Also, even if the marker indicated i was off the map, the uncharted areas of the map are revealed when I approach them.

Steps to Reproduce:
1. Given: 3, 2048x2048 maps, each charting a different area; 6 item frames; two locations ideally (centered at) x 0 z 0 and x2048 z 2048; 4 empty maps
2. Start with 3 charted maps, and copy each one
3. place the first set of copies in 3 item frames against a wall at position 1
4. place the second set of maps in 3 item frames against a wall at position two
5. There should now be 3, green, you are here arrows displayed on the wall maps.
6. use the remaining empty map to copy the map in which you are currently standing
7. move away from map display by a few hundred blocks, and use player held map that you just obtained by copying to check your position.
8. the map should only display a green arrow marking where the wall maps are, and a white dot indicating you are somewhere off the edge of the map even though you are within the bounds of the map youre holding.
