To fix tearing issue when
hashchange
is fired asynchronously.See this discussion whatwg/html#1792
TLDR; React schedules micro-task in between calls to
hashchange
event listeners, because in some browsers this event is fired asynchronously (e.g. WebKit does it). This results in teared state when some components receive updates faster than others and it happens within one micro-task.
