page breaks not detected?

[laudrain]

I have page breaks in content files with that tagging:

<span epub:type="pagebreak" id="page_51" title="51"/>

and a page-list in nav file.

But the ace.json report says:

 "properties": {
    "hasMathML": false,
    **"hasPageBreaks": false**
  },

sounds like a bug. I'll try to reproduce and will come back to you if I can't. Thanks!
