the flag dialog changes the site theme and the flagging_form doesn't work with the default link of flag friend

issue 1:
after the dialog form appears, some css were changed, until i reload the page. maybe the js of flag dialog or dialog api changes them. i'm not sure.

issue 2:
i use this module also for flag friend, and if i use the default link of flag friend, the dialog form will not be called and after it was confirmed, an error was showed.
