Magic glue fails when no SHAPE constraint is present #833
Description
Expected Behavior
Magic glue succeeds without a SHAPE constraint
Current Behavior
When there is no SHAPE constraint, the magic glue doesn't change the structure and fails with an error
Reproduction Steps
- Create a puzzle with no SHAPE constraint and a region where magic glue can be used
- Apply magic glue on two equal-sized regions
- Instead of changing the target structure, nothing happens and an error is thrown in the console
Environment
No response
Other information
It appears to be throwing in ConstrantBar#getShapeBox, presumably for PoseEditMode#flashConstraintForTarget which flashes the constraint box on target change
