[poppler] Spec question: Resetting form fields

I'm trying to get ready for 0.19.2 the patches to reset the form values and 
I've stumbled over something that feels like a mis-specification or maybe i am 
just reading the spec wrong.

The spec says

Upon invocation of a reset-form action, a conforming processor shall reset 
selected interactive form fields to their default values; that is, it shall 
set the value of the V entry in the field dictionary to that of the DV entry 
(see Table 220). If no default value is defined for a field, its V entry shall 
be removed.

So you go over the fields and if those fields have DV you set the V to that 
value and if not you remove the V value.

Seems simple enough.

But the V value is marked as inheritable this means that in this situation

Form A
V "Foo"
DV None

Form B inherits Form A
V "Bar"

When resetting Form "B" i'd remove the V value from it and it would show "Foo" 
since it will then be read from Form A.

That seems "wrong" in my mind. But obviously it's "wronger" going to Form A 
and removing the V there :D

So I'm quite stucked here. Any idea of what's the right thing to do?

Or maybe that is the right thing to do?
