{data-collapsed ="false" } work only last one content in ver 1.2.0
If I use jQuery Mobile 1.2.0, the "data-collapsed = "false" of "collapdible" contents work only last one content in "collapsible-set".
If I use ver 1.1.1, all contents collapse collectly.
Following page is sample of collapsible set page.
ver 1.1.1:
ver 1.2.0:
Please give me information about this disagreement between ver 1.1.1 and ver 1.2.0.
Thanks.
