Wiki "query" macro has problems

When adding a macro for a tickets query, it displays well in the preview, but when saved it has problems.

(private) example can be found at http://bitbucket.org/craiv/ibelieve/wiki/Test

You can reproduce this by:

• creating a new wiki page
• adding the default macro clicking on "list all issues for query"
• click "preview", admire good markup
• click "save"
• see the result

looking at the markup it seems that
{{{
<a rel="<b>Issue <a rel=">
}}}

is bad and making the remaining markup fail.
