Expected behaviour, as tested in Firefox 10, IE 10, Opera 11

When a stroke is applied to a canvas with the globalCompositeOperation set to:

- source-in
- source-out
- destination-in
- destination-atop
- copy

The composition does not occur as expected, with the destination image still visible where it should not be.
