Answer 1

Have come accross the same issue, coulnd't figured out what's wrong started blaming Babel ;)

Having code not returning any exception in browsers :

if (typeof document.body.onpointerdown !== ('undefined' || null)) {

issue was badly created || (or) part as babel creates its own type check:

function _typeof(obj){if(typeof Symbol==="function"&&_typeof(Symbol.iterator)==="symbol")

so removing

|| null

made babel transpilation worked.
