passive event listener

[songlilei]

when using iscroll on my mobile project, there always a err on the console

Unable to preventDefault inside passive event listener due to target being treated as passive

and then I checked the iscroll code ,and find out the err origin ,it from the row 473:if ( this.options.preventDefault ) { // increases performance on Android? TODO: check! e.preventDefault(); }
I guess the iscroll should consider the passive attr of the addEventListener, and promote the _move handler, please consider and promote the code, thanks.
