Related to this discussion I created: #1861
I started digging into the code a little and realised that
nodeData.onHandlerscan only hold one on-handler at a time since it is wiped every timeaddHxOnEventHandleris called. The fix is to just not do that ifnodeData.onHandlersalready exists.This is fixes the cause of the problem in the linked discussion because when there are multiple on-handlers on an element, only the last one is stored. So then only the last on-handler gets removed when the DOM updates. Every other on-handler just gets re-added without getting removed beforehand.
PS: I made this PR against the master branch, but please shout if it should be dev.
