User permission without ability to change author attempting to save entry resulted in missing author thus unable to see own entry in entry listing

[ngy]

Hi,

I'm testing using user without permission to "change author". When the user save an entry, the author section is null resulting in saved blog entry not being shown under the user listing in entry.
However admin is able to view all the entries created by user without permission to change author (all the entries created by this user has empty author). I hope my descriptions below are clear enough. Thanks.

Expected behavior

Just wondering if this is expected behavior? Coz I'm expecting creator able to see own entries even without permission to change author. Do advice. Thanks.

Steps to reproduce the issue

1. admin create a user (ie: usertest123) with staff status in Authentication and Authorization › Users
2. usertest123 login to /admin and create weblog/entry. After creating weblog entry, unable to see the entries created.
3. admin able to see all the entries created by usertest123
