Here's my simple component

    <DayPickerSingleDateController
      date={getDateFromUrl(this.props.router)}
      focused
      numberOfMonths={1}
      onDateChange={console.log}
      onFocusChange={noop}
    />

My URLs are in the format /date/${yyyy}/${mm}/${dd}, and the getDateFromurl("") function just transforms the URL into a momentObject.

Repro:

• Load page /date/2017/01/01, the DayPickerSingleDateController will highlight Jan 1st 2017.
• Navigate client side (i.e. no page refresh) to /date/2018/01/01

Expected result:

• DayPickerSingleDateController changes its visible month to Jan 2018

Actual result:

• DayPickerSingleDateController stays as Jan 2017.
• Jan 1st 2017 gets un-highlighted (this is good)
• If I manually scroll to Jan 2018, I see Jan 1st 2018 being hightlighted (which means the date prop has correctly been changed)
