Use of xsl:sequence within copy situations is node-destructive
When @$nodes instance of node()*@, then the following:
<a><xsl:sequence select="$nodes/></a> <b><xsl:sequence select="$nodes/></b>
$nodes only into the second element - within Dom node-insertion removes nodes from any trees they were in previously. With
xsl:copy-of the behaviour is as expected.

Clearly this can be fixed by creating a copy of the node before appending it.
It would be nice, however, to avoid doing a double copy in the case of
One way to achieve this would be to rewrite xsl:copy-of appearing within an element constructor as xsl:sequence at compile time (under appropriate circumstances) - which might be beneficial generally. In fact, I have a feeling we have started doing this for streaming purposes.

Fixes in makeComplexContent method of Expr.js. When adding an element to a parent, we can't just append an element directly. In the browser, for HTML elements, these should be copies of the original elements (constructed using DU.copyItem). Otherwise, use the Document.importNode method.
