Choosing the year 1AD...99AD in the year dropdown does not work

[schwarzenneger]

Create a datepicker with changeYear dropdown and an yearRange which starts from 1 using the following code (​http://jsfiddle.net/XHQkG/1/):

$("#datepicker1").datepicker({
    changeYear: true,
    yearRange: "1:2020"
});

When you attempt to select the year 1 through 99 in the year dropdown, the year 1901 through 1999 becomes selected instead (1 becomes 1901, 2 becomes 1902 and so on). It works OK for years >= 100.
