Status bar stuck on "Edit" state
Once a chapter has a workflow status of "Edit" in progress, the workflow state is stuck and cannot be changed. This happens as both admin and as the copyeditor, who should both be able to change this status.
To reproduce:
- Log in as admin
- Add a chapter and upload content
- Advance the status so that "Edit" is in progress
- Try to move the status forward or backwards from there
Expected: the status can be moved forward or back
Actual: Two overlapping modals appear, one of which is a "Change of workflow status" warning. Clicking OK to close the modal returns you to the book builder, leaving the chapter's status at "Edit".
