Updated month prop not updating the calendar when displaying multiple months

[geminiyellow]

6.x it work very well, but when i update to 7.x, the month cannot causes the calendar to re-render when its value changes.

i save the month in component's state, and it looks like: http://react-day-picker.js.org/examples/elements-year-navigation

but i set the numberOfMonths to 2. and then setState from captionElement.
the logs:

in handleChange i got the right date, 201706, then setState to component,
then the captionElement got the 201711 and 201712.

then i try to change not use state cause picker rerender, change to showMonth.
now it work.

ok, then i read the docs, and try to use onMonthChange to keep the currentMonth to the state, but WTF, you see that? captionElement use the old values.

there is no BREAKINGCHANGE in the CHANGELOG and there is no docs in anywhere.
so , i cannot use 7.x. @gpbl could you help me ?

my code:

ok, now i can say that is a bug.

from here: Fixed render of months when toMonth equals current month

@hydrognomik add this

+    } else if (props.toMonth && props.numberOfMonths > 1) {
+      const diffInMonths = Helpers.getMonthsDiff(props.toMonth, currentMonth);
+      if (diffInMonths <= 0) {
+        currentMonth = DateUtils.addMonths(
+          props.toMonth,
+          1 - this.props.numberOfMonths
+        );
+      }

Helpers.getMonthsDiff(props.toMonth, currentMonth) my toMonth is 201712, currentMonth is 201709, then the diffInMonths is -3, why you need to reset the currentMonth ? that is not right.

you should swap it to Helpers.getMonthsDiff(currentMonth, props.toMonth)
