Description
When using smaller image as no-repeat pattern in circle, it should show as normal image, but in firefox it is extended with edge pixels.
I've also constructed a test:
<!DOCTYPE html>

var pattern = ctx.createPattern(img, 'no-repeat');
ctx.fillStyle = '#0f0';
ctx.fillRect(0, 0, 100, 50);
ctx.fillStyle = pattern;
ctx.beginPath();
ctx.arc(0, 0, 50, 0, Math.PI * 2);
ctx.closePath();
ctx.fill();
ctx.fillStyle = '#0f0';
ctx.fillRect(0, 0, 16, 16);
_assertPixel(canvas, 1,1, 0,255,0,255);
_assertPixel(canvas, 20,1, 0,255,0,255);
_assertPixel(canvas, 1,20, 0,255,0,255);
_assertPixel(canvas, 48,48, 0,255,0,255);
});

<img src="/images/red-16x16.png" id="red-16x16.png" class="resource">but it needs to be ported into yaml and regen for all canvas variants.
Firefox/servo outputs:
while chrome passes as expected:
