Description
When trying to show the Callbacks on the Dash Dev Tools, the attached example generates an error and the callback map does not show up.
Tested with Dash 4.4.1 and both Firefox and Chrome. Also tried older versions of Dash (3.4.0 and 4.x with the same results). To reproduce, run the attached example.
Note: Comment out callback toggle_template_modal on lines 239-246 and the callback map will get generated. Removal of some other callbacks like save_proposed_mapped can result on other errors like: can't access property "order", g.node(...) is undefined

Research direction
Start by running the attached callback_map.py with Dash 4.4.1 and opening the Dash Dev Tools callback map in Firefox or Chrome. Exercise the callbacks mentioned in the report, including toggle_template_modal and save_proposed_mapped, and compare the resulting errors. Done means the callback map renders without the reported intersection or missing-node errors.
