Navigation parameter can open multiple sections

If the navigation parameter is used for the Accordian widget, and more than one section contains a match, multiple sections display as open when the Accordian renders.

To fix, modify line 31 of the 1.7.2 code to include an ".eq(0)" at the end so that only the first instance of a match is returned.

var current = this.element.find("a").filter(o.navigationFilter).eq(0);
