Greenhopper JavaScript sets browser title incorrectly for ampersand '&'

Greenhopper tries to display our project name, "Ticker & NLE", in the browser's title bar when on the Agile pages. But, the name is escaped so that it displays incorrectly. From the page source:

<script type="text/javascript">
document.title = "Ticker &amp; NLE - Chart Board - Vizrt JIRA";
</script>

This results in the text "Ticker & NLE" in the title. If I change the code to the following, it displays correctly:

<script type="text/javascript">
document.title = "Ticker & NLE - Chart Board - Vizrt JIRA";
</script>

Reproduction steps:

1. Create a project named "This & That".
2. Enable the project in Greenhopper.
3. Open project in Greenhopper's Agile view.

Expected behaviour: Browser tab displays "This & That - Task Board [...]".

Actual behaviour: Browser tab displays "This & That - Task Board [...]".
