Links in Kanplan acknowledge feature in dashboards are not working

Issue Summary

When a Kanban backlog board is being used in a gadget on a dashboard, a Kanplan acknowledge section is being rendered on top of it with the following text:

A bigger and better backlog has just landed
We've created a dedicated space for you to plan in the new Kanban backlog. This board will now be a distraction-free zone for your team to focus on work-in-progress.

That acknowledgment has links like "Take me there", "Close", etc, and none of them are working when viewed on the dashboard. The same links work fine when the acknowledgement is viewed in the board view.

Steps to Reproduce

1. Create a Kanban project
2. Create a Kanban board
3. Enable Kanban feature by dragging unmapped status to the leftmost column in "Columns" configuration of the board
4. Use this board in a dashboard gadget

Expected Results

Users are able to dismiss the alert when rendered on a dashboard.

Actual Results

Clicking on any links in the alert do nothing. Nothing is logged in the Javascript console either.

Workaround

It is possible to disable the banner altogether by modifying $JIRA_INSTALL/atlassian-jira/WEB-INF/application-installation/jira-software-installation/jira-greenhopper-plugin-xxxx.jar/atlassian-plugin.xml and commenting out all sections referencing KanplanAcknowledge resources:

<!--<resource type="download" name="KanPlanAcknowledge.js" location="includes/js/rapid/ui/kanplan/KanPlanAcknowledge.js"/>-->
<!--<resource type="download" name="KanPlanAcknowledge.soy.js" location="includes/js/rapid/ui/kanplan/KanPlanAcknowledge.soy"/>-->

Save the modified file in a JAR file, and restart Jira for change to take effect.
