Return URL missing when adding IP to VM interface

[tinyoverflow]

NetBox version

3.1.2

Python version

3.9

Steps to Reproduce

1. Open a virtual machine
2. Navigate to "interfaces"
3. Click on the + button on an interface to add an IP address

Expected Behavior

The return URL should be filled out so I get redirected back to the VM's interfaces page.

Observed Behavior

The return URL is missing and therefore after saving the new/assigned IP entry, I'll get redirected to the IP page.
