This did work in the past but at the same time, most gif files
were not supported at all so it is very unlikely that current
behaviour will change in the future (work-arounds are trivial
depending on what your gif files contain - technically).

Or in other words: It is a feature that we support many gif
files for which above syntax cannot work while we dropped
support for above use-case (that iirc would only work for a
small number of gif files).

Please remember that on this mailing list, only current
FFmpeg git head is supported.
