Question

Suddenly today out of nowhere I started getting this one on every page on our website

Added non-passive event listener to a scroll-blocking \'touchstart\' event.         


        

Answer 1

Ok digging this up a little more, this is not a new behavior, it has been reported a while ago and jQuery still hasn't fixed it.

The problem lies in the fact that for an handler to be passive it has to be certain of never calling preventDefault() but jQuery doesn't know in advance...

The only tip I could give you is change your console logging level and remove "Verbose". Follow up on this issue for ideas on solving this.
