Expected Behavior:
Jira filters can load data with less than 200 entries within a few seconds.

Observed Behavior:
Jira query “View Issues” in Overall Requirement Coverage Reports takes a long time to load (> 30 seconds) for 147 results.
Xray manages to load the graph instantly.

How to reproduce:
Choose „Overall Requirement Coverage Report“
Click on the blue bar in the chart (all / most entries)
A new section opens below.
Click on “View Issues” in the newly appearing section.
Loading the query takes a lot of time
The problem seems to be the following part of the query “… issue in requirements("UNCOVERED","","","","false")”
