[User-Picker CF] this field should not fetch inactive users.

Hi,

Currently, User-Picker field fetches all users including in-active ones. What is the use case in fetching inactive users?

I think the API should fetch active users only or its behaviour should be in align with 'Assignee' field.

Steps to Replicate

1. Create an User Picker custom field in a system with inactive users.
2. Click on the 'Select a user' icon ().
3. A pop up opens displaying all the users, including inactive ones (URL: http://<JIRA_SERVER>/secure/popups/UserPickerBrowser.jspa?formName=jiraform&multiSelect=false&decorator=popup&element=customfield_<CF_ID>).

Expected Results

Only the active users should be displayed - or it should be possible to at least filter inactive users out.
