I wouldn't worry about it. Just make this a utility function
and call it where appropriate. Traversal up the tree should take
almost no time.
The other option is to register all your event listeners on the
'groups' then 'currentTarget' will be the element you set the
listener on, but if you have many such groups it will be easier to
simply do the tree traversal.
