horizontal alignment of fields in admin change not working in 6.0

[Ronald Ligteringen]

To horizontally align fields in the admin change page you can combine these fields in a tuple, like this:

fields = ["name", ("age", "gender"), "nationality"]

In this example, the change screen would show something like this:

name:
age: gender:
nationality:

This works great in version 5, however this is not working in 6.0. This will show all fields vertically like this:

name:
age:
gender:
nationality:

Works fine for me with 6.0. Do you have a reproducer?

I'm seeing this same issue with fields rendered in a fieldset.
I figure it's caused by the fix for issue #36807.

from django.db import models
from django.contrib import admin

class FormMultilineTest(models.Model):
    date = models.DateTimeField()
    boolean = models.BooleanField(default=False)
    boolean2 = models.BooleanField(default=False)
    text = models.CharField(max_length=100)

class FormMultilineTestAdmin(admin.ModelAdmin):
    fieldsets = (
        (None, {
            'fields': (
                ('text', 'date',),
                ('boolean', 'boolean2'),
            )
        }
         ),
    )
admin.site.register(FormMultilineTest, FormMultilineTestAdmin)

Results in the first two fields being one below another, while the booleans are as expected:

The expected result (on 5.2.10):
