Bug 501776

SUMMARY
Editing the boundaries of an existing face rectangle then saving it results in a new face rectangle being added with the modified boundaries, rather than the existing face rectangle boundaries being updated.

STEPS TO REPRODUCE
1. Create a face rectangle.
2. Click "OK" in the face rectangle dialog.
3. Edit at least one boundary of the face rectangle
4. Click "OK" in the face rectangle dialog.

OBSERVED RESULT
A new face rectangle is added, reflecting the updated boundaries. The previous face rectangle still exists as well, with its original boundaries.

EXPECTED RESULT
The boundaries of the original face rectangle are updated (i.e., and there is only one face rectangle).
