Okay. Revision 9 adds code to remove the inserted elements, to put every test on equal footing. Is the practical equivalent yours? Because it hits a sweet spot.
The one called "MUCH MORE PRACTIVAL native equivalent" is a mistake, it doesn't do anything. I didn't know documentFragment lacks the innerHTML property so is not doing any parsing like the others.
Ah, that explains it. I can't submit Firefox results, though. The crappy native equivalent just locks up after throwing several "unresponsive script" warnings.
