I'm not sure exactly when you developed your solution, but between the release 
of 2.5 and 2.6 (11 November 2011) we added support for  the <span> tag. However
we don't support class as an attribute, but we do support style.

I have checked your example in revision 3774 (just prior to the change) and 
while it works it takes no notice of the span tag ie only the content of the tag 
'simplified' appears in the output.

Currently our 'span' supports various attributes, but not class. We have argued 
internally for an hour about the wisdom of adding the 'span' tag and not having 
an exact html match for all attributes, but the tag is now added and doesn't 
support all html attributes.

An easy fix would be to allow unknown attributes and just ignore them. I'll 
consult my colleagues about the possibility of doing that as a fix for your problem.
