5.2.3 revisions display incorrect user

[xxxLesy]

As of 5.2.3. revisions record incorrect user making post changes - always the original post author. Autosave records the correct user though. As does the "last edited by" on the all posts list. That is the case both in Classic and Guttenberg.

See attached screenshot.

Steps to reproduce:

1. Write a post with a contributor account and submit to review.
2. Open the post with an editor or admin account, make changes and save, plan or publish. All changes will be incorrectly shown as made by the original author.

16. S. I do have a lot of plugins, so it is possible some effect this, though none of them are suppose to interact with revisions. So please try to reproduce on clean install. If that is the case, I apologize.

I tried on a relatively empty test site of mine. For me WP 5.2.3 behaves correctly. See image.

Thank you for checking. I did more testing based on your input. Turns out it was Molongui Authorship (multi author plugin). Will report there.
