load_from_archive does not animate gif

[pcca-matrix]

when using load_from_archive , and animated gif is inside zip , it does not animate ! it work only if you specify file extension.

ex: tmp = front.load_from_archive( "F:/attract/layouts/test/test.zip","img.gif" ); Gif is animated as expected

tmp = _front.load_from_archive( "F:/attract/layouts/test/test.zip","img" ); Gif is displayed as static image.
