BlogPostLayoutFull is producing invalid XHTML when displaying a post path

The BlogPostLayoutFull macro displays the path to a post with the following HTML :

<div class="blogrefpath">
  <p>
    Posted in
    <ol  class="breadcrumb" >
      <li>…</li>
    </ol>
  </p>
</div>

This XHTML is actually incorrect as a <p> should not contain an <ol> tag.

Looking more in depth into this issue, it turns out that this is related to https://github.com/xwiki-contrib/application-blog/blob/0fbb196dcad438a84ee7b876e45ae0488af15056/application-blog-ui/src/main/resources/Blog/BlogCode.xml#L848 , for which the HTML macro with clean="false" will insert the <ol> block.

The BlogPostLayoutImage macro doesn't have the same issue (even though it is using the same code in Blog.BlogCode as the macro #displayEntryBlogLocation is called from within an HTML macro with clean="false" wiki="true". It turns out that this macro will not produce a paragraph within the <div class="blogrefpath">.

It is possible to check this behavior with the following snippet :

{{velocity}}

(%class='blogpostref'%)(((
Posted by {{html clean='false' wiki='false'}}<ol><li>Blog</li></ol>{{/html}}
)))

----

{{html wiki="true" clean="false"}}
(%class='blogpostref'%)(((
Posted by {{html clean='false' wiki='false'}}<ol><li>Blog</li></ol>{{/html}}
)))
{{/html}}

{{/velocity}}
