Not working when extras = 0

[cdvv7788]

When i have something like:

class AInline(NestedStackedInline): model = Column extra = 0 fields = ("content",)

class BInline(NestedStackedInline): model = Row extra = 0 inlines = [ AInline, ]

reversion.VersionAdmin,

class PageAdmin( NestedModelAdmin): inlines = [ BInline, ]

It won't show anything for the B model when i click "Add another B". For the A model it is working properly. The only way i could find to get a correct B inline was to use a non zero extra, but that keeps the error once i try to add more manually from the admin. I think it happens when you try to "Add another" that has an inline field

The issue seems to be in stacked inline. Tested in Tabular inline and it is working as intended (mostly)

Stacked in update seems to be working. Issue is on add parent form

"Add new A" is adding all A's inside first nest
