Fieldset '#collapsed' => TRUE Bug? w/ fix

After installing jQuery update my fieldsets could still expand and collapse but setting the default to collapsed wouldn't work. When looking at the code via FireBug I noticed that initially the div.fieldset-wrapper class styling is set to "Display:inline;" when default collapsed rather than "Display:none;" To fix the problem was a super minor change in the collapse.js.

~line 76: Originally:

.css({height: 'auto', display: 'inline'});

~line 76: Changed to:

.css({height: 'auto', display: 'none'});

Hope this helps someone. Cheers.
