Anything that modifies the native scrolling of a website can make a lot of trouble for some users, it's sometimes laggy, slow, or you simply can't scroll, it's a dangerous game.

Though we could discuss it all night long, in this particular case, people seem to be complaining about a chrome bug that doesn't let you scroll at all after you've done certain things ( can't really find steps to reproduce).

Which brings us again to the dangers of playing with scroll.

Chrome on OSX and chrome on android are quite the majority (and sometimes over represented on web-devs) so maybe that's why you don't see much issues.

This issue in particular happens to me with Chrome in Ubuntu.
