SortableInlineAdminMixin does not work with nested_admin NestedTabularInline

[smipi1]

I have tried creating a doubly-nested sortable inline admin using:

from django.contrib import admin
from translated_fields import TranslatedFieldAdmin
from nested_admin import NestedStackedInline
from adminsortable2.admin import SortableInlineAdminMixin

class LineInline(TranslatedFieldAdmin, SortableInlineAdminMixin, NestedTabularInline):
    model = Line
    extra = 0

class StanzaInline(TranslatedFieldAdmin, SortableInlineAdminMixin, NestedTabularInline):
    model = Stanza
    inlines = [
        LineInline,
    ]
    extra = 0

@admin.register(Poem)
class PoemAdmin(TranslatedFieldAdmin, NestedModelAdmin):
    inlines = [
        StanzaInline,
    ]

adminsortable2 throws an ImproperlyConfigured error (and rightfully so):

Class poems.admin.<class 'poems.admin.StanzaInline'> must also derive from admin.TabularInline or admin.StackedInline

nested_admin derives NestedTabularInline from InlineModelAdmin as can be seen here.

It appears that inheriting both the django and nested_admin classes prevents the adminsortable2 exception, but this breaks the nested admin inlines in the admin page:

class LineInline(TranslatedFieldAdmin, SortableInlineAdminMixin, NestedTabularInline, admin.TabularInline):
...
class StanzaInline(TranslatedFieldAdmin, SortableInlineAdminMixin, NestedTabularInline, admin.TabularInline):

Figuring out exactly how to work around this is way above my experience and skill, but I am very eager to assist in any way I can.

Is there a way to get the django-nested-admin and django-admin-sortable2 plugins to work together?

I'm using:

Django==3.2.3
django-admin-sortable2==1.0.2
django-nested-admin==3.3.3
django-translated-fields==0.11.2

I also logged an issue with the adminsortable2 project so that both projects are aware of the incompatibility.
