Issue Summary

Starting on Jira 8.7, we can no longer edit labels if the field is removed from screens, however, we still can reach the label's dialogue and add a label when we press the "L" key. 

While makes sense that after removing the labels field from the screen we can no longer edit it, it is still a contradiction that we can edit the same field using the short key "L". 

Reviewing the issue JRASERVER-28788, Nick Menere [Atlassian] (Inactive) added a comment - 23/Jul/2012 1:38 AM states:

We aren’t ignoring the setting. Any time the screen is used (except in view issue) it will only show fields defined on the screen.
The problem is occurring because we calculate whether a field can be inline edited by checking if it appears on the edit screen. This is wrong for labels. It should be defined by whether they have permission to edit labels for an issue. (as it used to work).

Later on, at the same issue JRASERVER-28788, David Elkan (Inactive) added a comment - 07/Aug/2012 3:41 AM explaining:

I’m sorry to say this however we won’t be able to bring back the edit button for the Labels field unless it is in the active Edit Screen. Instead the Labels field will operate as any other field and respect the Edit Screen configuration on the View Issue page.
To make the Labels field inline editable it must be added to the active Edit Screen. Also, as discussed above, you can press the ‘L’ key to bring up the Edit Labels dialog.
The issue JRA-28243 will track the creation of a Knowledge Base entry to cover ways to work around this issue in future.

This was said for Jira 5.1, however, the Labels field was visible up to Jira 7.13.8, then on 8.0, it was not more visible.

What’s the indented design, shall labels be editable inline on issue views?

Steps to Reproduce

1. Using Jira 8.0 or above, remove the Labels field from the screen used to view an issue type, for instance, bug
2. Create a new issue
3. View the issue
4. Hover the Labels field

Expected Results

The pencil would be presented and we would be able to add a new label

Actual Results

Labels files are not editable 

Workaround

Pressing the "L" key opens the Labels dialogue and you can edit the label.
