Have you checked the content of the objectStorage property in the
incoming object? Is it really empty or is it reconstituted from the
original object?
AFAIK if you don't submit a property in the request it's not processed,
so if you remove the property from the request object by deleting them
from the post array, I assume extbase is not treating this property at
all. I didn't have a look at the code though.
If the property is still part of the request, but your storage is not
emptied, it's a bug.
I could also assume that it's really a but and just a case of probably a
missing hidden field in the form storing the initial count or something.
Just like it's done for checkboxes or with the __identity fields. Some
field that's indicating the property was there, even if no child objects
where submitted, something like:
<input type="hidden"
name="tx_exkey_whatever[object][objectStorageProperty][__count]"
value="count of initial storage" />
