Is this buggy behaviour? I cant see why this fails...

1) Import a photo.
2) Freehand draw a shape to surround an interesting part of the image.
3) Intersect the two.
4) Use the Photo tool to crop one edge of the Clipped Photo

Now I want to refine the clipping shape, so I switch to the Shape tool, but there are no longer any nodes to edit!

Switching to Wireframe shows that the clipping shape is still there, and the mouse pointer indicates that I can reshape the lines, but the behaviour is erratic to say the least!

I posted a video (~4MB) showing what I mean HERE
