Design studio 1.6 SP3 bookmark is not working for Windows SSO

Experts,

i created bookmark in design studio V1.6.3.1, i have copied the link in my web browser (IE 11) & ad d as favorites. i closed all my IE & open new IE with my bookmark is asking for user credentials.

Looks like windows authentication/SSO is not working only for generated bookmark other links like any opendoc or launch pad are working.

bookmark link:

Bookmark.shareBookmark(Bookmark.getBookmarkUrl(DROPDOWN_1.getSelectedValue()));
