XState version

XState version 5

Description

Coming from: statelyai/docs#469
I initially thought this was expected, but looks like it's not... so I'm opening an issue here.

I left a test in you can run:

This line is using self.send, but using enqueue.sendTo(self, …) will also produce the same warning.

Expected result

There should be no warning.

Actual result

I'm getting a warning that custom actions should not call assign
