| // of an animated PNG in which the IDAT frame is not part of the animation. This |
| // should only happen if we do *not* support APNG. Now that we support APNG, |
| // this test fails. |
| // |
| // The ImageDecoder is not aware of what method is requesting the decode, and |
| // the APNG specification [1] does explicitly state that the IDAT is not part |
| // of the animated image if there's no fcTL chunk preceding it. It would make |
| // more sense if this test would verify that the first frame of the image is |
| // drawn, but that is explicitly not the purpose, as stated at [2]. In Firefox, |
| // the developer of the APNG specification, this test [2] fails too. |
