This would require that the WebCore DOM notify the GObject bindings when a DOM
property changes.  It's unlikely that we'd be able to do this without a
substantial performance impact on DOM operations, even when no-one is listening
for notifications.  The DOM itself supports mutation events that are fired when
attributes are added, removed or modified, but as they have a measurable
performance impact even if unused we have chosen not to support them at this
time (they're #if'd out in the code).
