Cannot apply Size and Position filter to color clip

I cannot apply a Size and Position filter to a color clip generated by the Open Other… Color function. Is this intentional or a bug?

Works for me. Just make sure you select ‘fill’ for the size mode

(the audio track is irrelevant in this screenshot)

That’s odd. It works with fill and distort. but not with fit.
Guess it’s not a bug.

Do you happen to know why fit does not work?
