hi guys.

I just upgraded our project from mongoid 5.1.4 to 6.0.3. And we got a bunch of tests failing. It looks like if you have an embedded document with before_validation callbacks, changes in the before_validation callbacks are not persisted anymore if you run a update_attributes on the parent model object.

The changes are persisted alright with mongoid 5.1.4. So I guess this is a new change in version 6.x?

Is this an expected behaviour? or we are doing something wrong here?

I added a PR for this ( https://github.com/mongodb/mongoid/pull/4398 )

In this PR, I added a before_validation on the book page model, and two specs for it. The one with database reloading is failing.

(I know for this test, you could use a default value to replace the before_validation. But this spec is not talking about the business logic. It's just an example.)

Thanks a lot in advanced.
