Crop offset issue when loading state file

[harripj]

Describe the bug The crop offsets do not appear to be maintained when loading the state file.

In fact the correct crop offsets are maintained when viewing the crop in the pipeline, but the rendered volume appears to be located at the origin (0, 0, 0).

To Reproduce Steps to reproduce the behavior:

1. Load two datasets, eg example datasets
2. Crop one volume
3. Save state
4. Load state to see that volume has been shifted to (0, 0, 0)

Expected behavior The volume is rendered in its position when saving the state file.

Screenshots Crop settings:

Additional context As mentioned, the correct crop values are maintained in the state file on load, but the volume is incorrectly positioned.
