Toggle: fixes #4131 working example accordion markup
Details: fix open/close on devices with touch events

The `touchstart` event has `event.which = 0`, which was passing
as a falsy experssion for the if statement's `!which`.  The `click`
event would then follow and undo the `touchstart` event's change.
