Read-only view of generic object list template pushes table beneath right-column search

[tomryder-inspirenet]

NetBox version

v2.11.0

Python version

v3.7.3

Steps to Reproduce

1. Set a user with read-only permissions on e.g. IPAM > Prefixes
2. Log in as that user
3. View the list of IPAM prefixes

Expected Behavior

The data table appears to the left of the search box in the right column.

Observed Behavior

The data table appears below the boundary of the right search box, as if it were not correctly floated.

This does not happen if the user has create/edit permissions for the object type.

Reverting 0bb2a05, the fix for #6171, fixes this issue—but might cause a regression on that one.

Perhaps the scope of the permission condition testing needs to be adjusted.
