output order preface epub3

Hi guys,

    

    Not sure if this is a bug or my xml. The structure is below:

    

    <preface>

    <title>Foreword</title>

    

    <para>...</para>

    <para ....</para>

    

    <section>

    <title>...</title>

    <para>...</para>

    <para>...</para>

    </section>

    

    <section>

    <title>...</title>

    <para>...</para>

    <para>...</para>

    </section>

    

    <section>

    <title>...</title>

    <para>...</para>

    <para>...</para>

    </section>

    

    <para>...</para>

    <para>...</para>

    <para>...</para>

    </preface>

    

    In the epub 3 the paragraphs at the end are outputted after the
    paragraphs at the start before the first section. Do I need to just
    wrap the first and last paragraphs into a simplesect to avoid this?

    

    It works fine in the FO output.
