Scroller extension causes uncaught errors in xhtml files

Using the scroller extension with an xhtml document causes an exception when the table has less than 3 rows. The offending code is on line 1029 of the Scroller 1.5.1 source: https://github.com/DataTables/Scroller/blob/1.5.1/js/dataTables.scroller.js.

This error is caused by invalid xml due to a   character reference.

Changing the named entity to the numbered entity ( ) has fixed the error in my local setup.
