Not able to assign users if the current assigned user loses "browse projects permission" after assigning to another user

Summary

Not able to assign issue to another user via the "Assign" button if the current assignee loses "browse projects permission" after assigning the issue to another user.

Steps to Reproduce

• Give "Browse Project permission" to current assignee only.
• Give "Assignable User permission" to any logged in user
• Give "Assign Issues permission" to current assignee only.

1. Assign any an issue (Issue_A) to user_A.
2. Login as user_A and browse (Issue_A).
3. Click on the "Assign" button, set assignee to user_B and assign.

Expected Results

• User_A cannot view Issue_A (because user_A does not have Browse Project permission).
• User_B is new assignee to Issue_A.

Actual Results

• Receive error message
