Very interesting.  It does appear that the stylesheet
is violating the XSLT spec, because it is using
xsl:apply-imports in a template that is called and
not matched (see the XSLT spec section 5.6).
I'd like to know why the other processors didn't flag
this as an error.

You could try copying the template named chunk-element-content
from html/chunk-common.xsl to your customization layer
and modifying the default value for the content parameter:

Change:

<xsl:template name="chunk-element-content">
  <xsl:param name="prev"/>
  <xsl:param name="next"/>
  <xsl:param name="nav.context"/>
  <xsl:param name="content">
    <xsl:apply-imports/>
  </xsl:param>

To:

<xsl:template name="chunk-element-content">
  <xsl:param name="prev"/>
  <xsl:param name="next"/>
  <xsl:param name="nav.context"/>
  <xsl:param name="content"/>


My reading of the stylesheets shows that, with one exception,
this template is always called with the content parameter
set, so making the default null should be no problem.
The one exception is in the separate chunktoc.xsl customization
that is used to manually chunk content.
