The Jira macro inserts a paragraph when used in inline mode

Steps to reproduce:

1. Use the Jira macro inline with "enum" style in a paragraph as on https://extensions.xwiki.org/xwiki/bin/view/Extension/Security%20Module#HCache
2. View the page.

Expected result:

The macro doesn't cause any line break.

Actual result:

The Jira macro is on its own paragraph.

This only seems to be an issue when the macro is rendered async as it can be seen on https://extensions.xwiki.org/xwiki/bin/view/Extension/Security%20Module?async=false#HCache. I think the main problem is that the inline information is lost in the async rendering context.
