The delete method should not be called at all for now, see bug #46497.

It seems to be called once for every level in the hierarchy, i.e. with another level

handle -> subclass -> subsubclass -> subsubsubclass

destroying subsubsubclass results in subclass.delete being called three times.

(file #44192)

If you have a class hierarchy like:

handle -> subclass -> subsubclass

where subclass implements a delete method, this delete method is incorrectly called twice when a subsubclass object is destroyed. See attached files for an example (and here's a command line example showing the same issue, using these files).
