Hovering the SLA field in Issue View does not display due date information

Issue Summary

On latest versions of Jira, when hovering the SLA field on a ticket in Jira Issue View, it doesn't show the exact due date anymore as it used to do before (Jira 8.12 for example). The expected information shows up when hovering the SLA in the queue/search view.

Steps to Reproduce

1. Setup a JSM project with tickets and SLAs implemented
2. Hover the SLA field in the Issue View of a ticket

Expected Results

See the due date full information, as it currently still shows up in the queue/search view:

Actual Results

The hovering information is missing the complete information:

Workaround

Check the complete information of the SLA due date on the board view.
