Macro alone in a paragraph is badly parsed

The following XWiki 2.0 syntax:

(% style="color:red;" %)
{{velocity}}$xwiki.version{{/velocity}}

after

Generates this HTML in view mode:

<p>2.3-SNAPSHOT.27857</p>
<p style="color:red;"></p>
<p>after</p>

Notice the empty paragraph. The style wasn't applied to the paragraph containing the macro but instead an empty paragraph was added. This works fine in 2.2.2.
