JavaScript error is displayed on JIRA Agile Boards after installing JIRA Service Desk

Symptom

Red error dialogs appear if you install JIRA Service Desk after JIRA Agile.

• A red error dialog appears for only a moment when you go to the scrum board and only when you use Chrome (See problem.mov)
• Another red error dialog appears when you visit "Manage Boards" when you use Chrome (See problem3.png)
• Another red error dialog appears when you create a subtask from the backlog and only when you use Japanese (See problem2.mov)

Excerpt from the error message:

An exception has occurred in http://127.0.0.1:8080/s/389cefa756e99d05441edefd08894435-CDN/en_US-vyuule/64020/28/27dffb62c6d53c3687501abc152a3948/_/download/contextbatch/js/greenhopper-rapid-non-gadget,gh-rapid,atl.general,jira.project.sidebar,jira.global,jira.general/batch.js?jag_disabled_marketing=true&locale=en-US&isAdmin=true at 9194:277 --- Uncaught TypeError: a.hasAttribute is not a function

Step to Reproduce

This is how I reproduced:

1. Install vanilla JIRA 6.4.6 (current latest)
2. Install JIRA Agile 6.7.4 (current latest) at 'Find add-ons'
3. Create a scrum board and create a project for the board
4. Create an issue, which will be stored in the backlog
5. Create a Sprint, move the issue to it, and start it
6. Install JIRA Service Desk 2.5.0 (current latest) at 'Find add-ons'
7. Using Chrome, go to the backlog and see the red error dialog appears for only a moment (See problem.mov)
8. Using Chrome, go to the "Manage Boards" and see the red error dialog appears (See problem3.png)
9. Go to profile page and change the language to Japanese
10. Go to the backlog and create a subtask, and see another red error dialog appears (See problem2.mov)
11. The subtask is successfully created when you refresh the backlog page

Findings

• It happens if you install JIRA Agile and then JIRA Service Desk
• It does not happen if you install opposite way (JIRA Service Desk -> JIRA Agile)
