Environment

Python version: 3.7.5
NetBox version: 2.9.7

Steps to Reproduce

Create a custom script utilising MultiObjectVar. Example ob_var.py:

from extras.scripts import *
from virtualization.models import VirtualMachine

class ObjectVarTest(Script):
    vm = MultiObjectVar(
            model=VirtualMachine
            )

    def run(data, commit):
        pass

Find the ID of one of your Virtual Machines
Try using the URL https://your.netbox.install/extras/scripts/ob_var.ObjectVarTest/?vm=13

Expected Behavior

That the initial field for a Virtual Machine would be pre-filled with my VM number 13.

Observed Behaviour

Nothing is pre-filled.

Change the MultiObjectVar to ObjectVar and repeat the test - the field is pre-filled with the Virtual Machine.

It seems that the field does accept initial data, but treats the value as a list, so muilt-character values don't work correctly. E.g. ?vm=9 works but ?vm=10 does not because it's interpreted as passing [1, 0].

I've dug into this a bit but can't account for the bug: AFAICT the form field is being initialized with the correct data. It may be related to the Select2 library. This isn't limited to custom scripts, either: Config context object selection is another example where multi-character initial values don't work.
