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

[stodge]

I'm getting a warning from Firefox:

 Added non-passive event listener to a scroll-blocking 'touchstart' event. Consider marking event handler as 'passive' to make the page more responsive. See https://www.chromestatus.com/feature/5745543795965952

eventManager | @ | Event.js:290
root.add | @ | Event.js:45

Any plans to address this in the near future? Thanks
