Snap object to origin in web

I am using the free web client and trying to move an object so that its corner aligns with the origin. No matter what I try, it will not snap to the origin. How can I do this?

It should snap if you grab it by the corner. Alternatively you can grab it by the corner that you want to be at the origin and start moving it with the Move tool. Let go of the mouse and type [0,0,0] including the square brackets.
