Hmm, this comes from a Safari merge in the first place :) 
(Well, more precisely a discussion with Maciej about scope in event handlers,
on which we agreed)

I moved that code as part of revision 406282, and Webcore-315 definitely has 
the storage of the originalNode in JSLazyEventListener.
Are you looking at an older webcore? Or an even-more-recent one than 315?
