Inconsistency of the background color when the bottom banner is active

[julianstolp]

NetBox version

v3.3.9

Python version

3.8

Steps to Reproduce

1. Enable Bottom Banner in Config Revisions or go to demo.netbox.dev
2. Click on any sidemenu
3. Compare before and after

I think the background color is inherited from the body styles instead of the container-fluid class. Which is true for the top banner but not for the bottom banner.
