This is a change to how Chrome deals with sites that use onScroll. In their current state, most of these are broken as far as I'm concerned. Chrome's changes will partially fix a lot of these sites, at the cost of breaking some that aren't currently broken. That is a win for the user. My only problem with this change is that developers can still override the default and cancel scroll events. The handful of legitimate use cases this enables aren't worth the cost of letting shitty designers abuse it.
