Issue Summary

Currently, the number of pinned fields is limited to how much space each field's id store in api/2/mypreferences. Since this has a limit of 255 characters, depending on which fields are pinned, one user will be allowed to pin more fields than another user.

Expected Results

Jira should set a specific limit of how many fields might be pinned. 

Actual Results

User A might be able to pin 7 fields while User B might be able to pin 11 fields.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
