Elements with epub:type in <aside epub:type="footnote"> are not supported

Hi,

the following HTML snippet throws an error in Thorium-1.3.0-alpha.1.2291:

<p id="abs_5-379" class="firstInSequence">Text vor Endnote <span id="fn_elNr-1-2-1-2-1-2-2" class="endnote"><a epub:type="noteref" role="doc-noteref" href="#fn_elNr-1-2-1-2-1-2-2_target">1</a></span> Text nach Endnote</p>
<aside class="endnote" id="fn_elNr-1-2-1-2-1-2-2_target" epub:type="footnote" role="doc-footnote" aria-label="Footnote 1">
  <div class="footnote_counter">
    <p><a href="#fn_elNr-1-2-1-2-1-2-2" epub:type="referrer" role="doc-backlink">1</a></p>
  </div>
  <div class="footnote_content">
    <p id="fn-abs_7-381">Text in Footnote</p>
  </div>
</aside>

Adding the xmlns:epub namespace on the a element does not help.

If I remove the epub:type="referrer" it works:

It seems that every epub:typeattribute is not supported in the footnote/endnote popup. Any chance to get this fixed?

Hello, I copy-pasted your HTML snippet into a test EPUB, and I am seeing this error in the console:

Error: Failed to execute 'insertAdjacentHTML' on 'Element': The provided markup is invalid XML, and therefore cannot be inserted into an XML document.

Error: Failed to set the 'innerHTML' property on 'Element': The provided markup is invalid XML, and therefore cannot be inserted into an XML document.

…I’m investigating.

Thanks for letting us know. Note that r2-testapp-js is a maintained lightweight Electron app (reader window, no library / bookshelf view) used to test-drive the internal Readium2 components, so it includes this bugfix. https://github.com/readium/r2-testapp-js/releases
