The highlighting of the Sprint options is not following the cursor and gets stuck

Issue Summary

The highlighting of the options in the Sprint "3 dots" menu is not following the cursor and gets stuck when hovering (mouse overing) up and down each option.

Environment

• Replicable on Jira Data Center 9.4.x
• Not Replicable on Jira Data Center 8.20.x
• Not Replicable on Jira Data Center 9.12.x

Note

This bug might be related to JSWSERVER-25774, as the symptom is similar.

Steps to replicate

• Create a new SCRUM board
• Create a few Sprints on the board
• Next to any Sprint, click on the ... menu
• Hover up and down over each of the options listed in this menu:
  • Edit Sprint
  • Move Sprint down
  • Delete sprint

Expected behavior

The highlighting should follow the cursor:

• if the cursor is on "Edit Sprint", then the highlighting should on "Edit Sprint"
• if the cursor is on "Move Sprint down", then the highlighting should on "Move Sprint down"
• etc...

Actual Behavior

The highlighting is not following the curstor and gets stuck.

For example, when the cursor is hovering from the top to the bottom of this menu, and then backup, the highlighting gets stuck on the option located at the bottom, which is "Delete Sprint".

Workaround

Upgrade Jira Software to the most recent LTS release (9.12.x).
