broken dynamic size rgba input into rotate

In latest ffmpeg, rotate filter doesnt handle rgba input of a dynamic size. The output appears very broken:

ffmpeg -filter_complex "color=c=black:size=200x200:rate=30[b];color=c=red:s=100x100,scale=width=n:height=100:eval=frame,format=rgba,rotate=a=n/10:ow=100:oh=100:c=#00000000[r];[b][r]overlay" -t 4 -y rgba.mp4

The issue seems to be introduced by format=rgba.

I understand in this particular example format=rgba is unnecessary, but the provided example is a demonstration of an isolated issue.

Please refrain from opening more tickets about dynamic w/h changes midstream. One open ticket is enough.
