DCIM Interface: ObjectChange missing for deleted untagged VLANs

[moonrail]

Deployment Type

NetBox Cloud (demo), Self-hosted

NetBox Version

v4.2.0 (demo.netbox.dev) & v4.1.11 (locally)

Python Version

3.11

Steps to Reproduce

1. Have an Device with an Interface
2. Have two VLANs: A & B
3. Set Device Interface mode to "tagged"
4. Add VLAN A as untagged VLAN to Interface
5. Add VLAN B as tagged VLAN to Interface
6. Delete VLAN B
7. Delete VLAN A

Expected Behavior

Interface ObjectChange update for each VLAN deletion:

1. tagged_vlans to empty list
2. untagged_vlan to null/None

Observed Behavior

Only one Interface ObjectChange update is created for VLAN deletion: tagged_vlans.

No Interface ObjectChange is created for untagged_vlan when related VLAN is deleted. According to Interface Changelog the Interface still has an untagged_vlan when in fact it does not exist anymore.
