Please be careful when you put words in my mouth.  Not advocating,
simply observing that this happens in some (quite limited, actually)
circumstances.  The observed change happens _only_ if you introduce an
aria: attribute into an XML DOM by parsing a document with such an
attribute present, _remove_ the resulting attr node programmatically
using removeAttribute, and then add it back using setAttribute.  This
has got to be a pretty unusual sequence of events: by far the more
common pattern is to use setAttribute only to change the value, and
that does _not_ provoke the change we're talking about.
