React-datepicker: Problem with datepicker on firefox with october month

[kauehmoreno]

Whenever October month is shown there is a bug which does not show all days, it can be seen it on mainpage of react-datepicker . https://hacker0x01.github.io/react-datepicker/

Both 2017 and 2018 are wrong on displaying all days as we can see on images attached

This only happens on firefox so far.

What version of Firefox are you using?

I just tried with Firefox 55.0.3, and it looks normal to me.

I've just check my version, and it's a little bit old.. I'm using 46.0.1 . I will update and check it out

I've just updated to 56.0.1 and still happening to me

Hi, i'm having this issue in Firefox as well. Using 56.0.1.
Worth mentioning that in October, in Brazil (GMT-3) we have daylight saving time beginning. Maybe it's a problem with moment.js.

That seems like a good clue. In the screenshot the calendar is displaying duplicate rows for the week of 8-14, probably due to incorrect day arithmetic around DST.

@gabriel-card Can you check whether #1066 fixes it for you?

[gabriel-card]

@aij hi!
Just tested from master, didn't fix. Could it be moment.js's locale settings?

edit: just saw my code, i'm setting it globally to 'pt-br', so it should work just fine. This is mindbogging.
