In https://bugzilla.mozilla.org/show_bug.cgi?id=725221 roc (cc'd, not  
subscribed to the list) suggests optimizing textContent by special casing  
the scenario where the first child is a text node and the string being set  
is non-empty. This would affect mutation observers and makes the setting  
algorithm more complicated, but it is also a performance win (in some  
implementations at least). Opinions?
