29447	RelatedManager.set() doesn't pass bulk keyword argument to clear()	Jeremy Lainé	nobody	"For reverse many-to-one relations, the `set` method's `bulk` keyword argument is passed down to the `add()` and `remove()` methods. It isn't however passed down to the `clear()` method:

https://github.com/django/django/blob/265506bbc347a6b3fcc6c66ab1a2417b3b7ea57a/django/db/models/fields/related_descriptors.py#L711

This looks like a bug, as passing bulk=False, clear=True results in the following behavior:

- clear() is invoked in ""bulk"" mode, not triggering signals
- add() is invoked in ""non-bulk"" mode, signals are triggered

Admitedly, I'm not too sure why you would want to do this, but at the very least the docs should mention if this combination is unsupported.

I spotted this while reading the `related_descriptors.py` code to fix #29440.
