Issue Assignee and Reporter is kept when moving an issue, even though user has no permission

Summary

Issue assignee and reporter is kept when issue is moved to another project, which in the new project, this current assignee and reporter has no permission (Assignable User, Create Issue)

Environment

JIRA 6.4.4

Steps to Reproduce

1. Create User A, B and U
2. Create Project P and Q
3. User A is in the Project Lead, Developer and default assignee roles for Project P
4. User B is in the Project Lead, Developer and default assignee roles for Project Q
5. User U is in the User role for Project P
6. Have User U create an issue in Project P, so it will be assigned to User A automatically
7. Have User A move the issue to Project Q

Actual Results

Issue is moved to Project Q successfully, without the need of changing the assignee or reporter of the issue

Expected Results

1. In the Move Issue action, enforce the need of changing the Reporter and/or Assignee to fit the configuration on the target project. OR
2. Set the Assignee and Reporter field to the default role for that project

Notes

Need to update Moving an Issue documentation in JIRA, to reflect the correct expected behavior
