Issue

In Confluence (found with OnDemand) if you insert the JIRA issue macro by typing in:

{jira:TPO-2}

...with TPO-2 being the issue key, the displayed macro is broken. It appears to have an '=' sign inserted in, making it render incorrectly.

This behavior is also duplicatable by selecting WIKI MARKUP then typing in the string.

However, if you use the INSERT - JIRA ISSUES MACRO button, the display behavior is normal. See screenshot. I was able to reproduce this on toolbox.atlassian.net and a customers instance.

Workaround

Use the INSERT - JIRA ISSUES MACRO button in Confluence. Alternatively, if you select the broken macro image, select EDIT then save it, it removes the '=' and renders correctly.
