InlineTabular and ManyToMany Form Field Layout messed up.

[LuxsSoft]

Hi

First of all, thanks for maintaining this package!

I am experiencing issues with the Layout with django-jet-reboot version 1.3.3.

TabularInlines are not shown as tabs but rather appended at the bottom of the page and the many to many admin form widget is squeezed, not showing single selected values in the box.

I expect the following layout:

But what i get is this:

Interestingly the issue is not present when developing locally and serving on localhost. However on the server running nginx reverse proxy it is messed up like described. I don't know what could cause this difference. I am running in a virtualenv with dependencies managed by poetry. So dependencies should be all else equal. Django version is at 3.2.16.

Any ideas? The tabs are not a big issue but this many to many form widget is almost impossible to select multiple values properly.

Thanks in advance!
