IndexOutOfBoundsException in PdfBoxFastOutputDevice using PDF/UA

Using Java 8, Windows, openhtmltopdf v1.0.10.

I tried recreating the example from https://github.com/danfickle/openhtmltopdf/issues/352

HTML:

<html>
<head>
<style>
@page {
  margin: 50px 20px;
  @bottom-left {
    content: element(whatever);
  }
}
</style>
</head>
<body>
<div style="position: running(whatever);">
  This is some <strong>richly</strong> styled html!<br/>
  <span style="color: red;">This is another line.</span>
</div>

<h1>Rest of content</h1>

<p>Etc, etc, etc...</p>

</body>
</html>

with the Java code:

PdfRendererBuilder builder = new PdfRendererBuilder();
builder.usePdfUaAccessbility(true);
builder.toStream(out);
builder.run();

and I get the exception:

"Workaround": Removing builder.usePdfUaAccessbility(true); creates the PDF.
