Issue Summary

When users press the A action to assign issues from the backlog, the assign button is often not visible.

Steps to Reproduce

1. This issue is occurring intermittently. When you open the backlog and refresh or reload the page → press A -> the assign pop-up doesn’t load correctly.
2. If you refresh the page after the assign pop-up does not render correctly → select a ticket → close the ticket window on the right side of the page → press A → the assign pop-up loads correctly.

Expected Results

The Assign pop-up should load correctly, displaying the Assign button.

Actual Results

After a page refresh and using the Assign keyboard shortcut, the Assign pop-up is not loading correctly and the Assign button is missing. 

Workaround

Refresh the page → select a ticket → press A shortcut, and the assign pop-up will load correctly for all the tickets in the backlog unless you refresh the page or open the backlog without selecting or highlighting a ticket. Switching between the options below the Backlog (Active Sprints, Releases, etc.) doesn’t affect the rendering of the assign pop-up. 

It appears that keyboard shortcuts in Jira (such as "A" for assign) are designed to function when an issue is selected. If no issue is selected, the behavior may be undefined or result in UI glitches. However, the Assign pop-up should still load correctly.
