Calendar Month View Context filter issue

When using /calendar/month view and set the context filter to a month with less than 31 days - example: set uri to calendar/month/201609 on 8/31/2016 (set the server system time), the calendar will not render.

This seems to be an issue with DateArguementWrapper function createFromFormat($value) when format arguement is 'Ym', a quick work around may be if the format is 'Ym', append 01 to value (so it's first day of the month) and then generate the date object using Ymd?
