JQuery UI Datepicker Incorrect Century

On certain yearRange options

This is a known bug bugs.jqueryui.com/ticket/8873, but I couldn't find it on a search, so it might be helpful to post here.

I was creating a datepicker for a date of birth field, with no default value, and with a yearRange of "c-100:c-1". However, the year dropdown kept on jumping to 100 years before the actually selected year. I changed the yearRange option to "c-100:c" and it then worked fine.
