"onTouchStart" preventDefault is ignored, causes double step to happen

[adnansorg]

This was tested on Chrome 58 with responsive mode switched on which means it treats clicks as touch events. This results in step being done twice on a single click.

The following message gets logged in the console.

[Intervention] Unable to preventDefault inside passive event listener due to target being treated as passive. See https://www.chromestatus.com/features/5093566007214080

Same issue here

Reproduced in react-numeric-input v2.0.9 and 2.1.0 in desktop Chrome in device mode and latest Chrome browser on Android.

Hi @vlad-ignatov,

Made a quick fix on this issue according to recommendation on developers.google.com:
https://developers.google.com/web/updates/2017/01/scrolling-intervention

If your touchstart listener calls preventDefault(), ensure preventDefault() is also called from associated touchend listeners to continue suppressing the generation of click events and other default tap behavior.

Please review and merge if appropriate, this fixes the double click issue in devtools' device mode so should work on mobiles with touch events: #56

This is now fixed thanks to @lanceon.
