Markers don't retain their dimension

Describe the bug
When setting a dimension for a marker, then saving and reloading, it is set to 0 again.

To Reproduce

1. Create a marker
2. Set it's dimension to something that isn't 0
3. Save the map
4. Load the map
5. Notice that the dimension is set back to 0

Expected behavior
The marker to still be in whatever dimension I put it into

Screenshots
N/A

Version
Server: Windows 10, 1.5.7
Client: Windows 10, 1.5.7

Additional context
Opening a map that already has a marker set to another dimension will have it be loaded into that dimension.
However, trying to modify that and saving it (e.g. from 40 to 3) will not save the new value either.
