Circular mask feather clips out of frame when expanded to the edge.

I wanted to have an iris transition via a circular mask to have better control over the feathering and accelleration, but when the mask touched the screen, the feather completely disappeared for that little bit. I can't imagine why it would be this way other than a glitch. Creating a dynamic link to after effects completely fixed the issue, so I am reporting it here as a bug. Here are some screenshots I took of the issue.

Please fix this. It is extremely aggervating to have to resort to going to another software to fix an issue that shouldn't be here in the first place.
