Steps to reproduce:

ctx.fillStyle="#880088";
ctx.fillRect(0,0,75,75);
ctx.fillStyle="#888800";
ctx.arc(100, 100, 75, 0, Math.PI*2, false);
ctx.clip();
ctx.globalCompositeOperation = "multiply"
ctx.fillRect(0, 0, 100,100);


Actual results:

The blending occured taking into account the clipping


Expected results:

The clipping path was completely ignored (Or, the blend mode, when used with the "lighter" blend mode).
