Description Rebecca Hauck 2014-05-01 10:38:02 PDT

From the spec:

For animated raster image formats (such as GIF), the first frame of the animation sequence is used.

The attached test uses a 3 frame animated gif for shape-outside where each of the frames causes the 2 lines of text to wrap differently. You can see the shape animate and it ends up taking the last frame as the shape.

Even though the behavior doesn't match with the level 1 spec, we've agreed on keep this "bug" as it is, since it's actually a feature, and will be included in the future versions of the spec.
