When showing multiple months and the current month is not displayed first (e.g. because of maxDate: 0), the user needs to click the previous button multiple times in order to see any effect.
In this example 3 clicks are needed https://jsfiddle.net/m3528fdb/, which makes the button seem broken initially. The number of required clicks depends on the values for stepMonths and maxDate.
