# exercises: The reverse of container-vp8x-still-flags, which sets flags
#   with nothing behind them. Here the data is there and the flag is not.
#   Nothing in the demuxer compares the two, so the frames blend exactly as
#   they would with the flag set; webpinfo refuses the file -- "Unexpected
#   alpha data detected" -- which makes this the pair of cases where the two
#   readers here disagree in opposite directions.
