Comment (by shawfactor):

 Even if 97% is not enough I'd assume that it is possible to test support
 and fallback to unload where appropriate. Note my javascript is not up too
 the task of fixing this myself unfortunately.

 Ideally the whole api would be rewritten without a jquery dependency, but
 that should probably be kept as a separate issue.
