I came across this bug description when searching for a potential bug related to CanvasRenderingContext2D::arcTo.
If that is not already done, I can propose a patch fixing this bug and adding corresponding test cases. Probably the test cases could follow the style of the current canvas test suite, something like a green rectangle generation:

<canvas id="myCanvas" width="100" height="50">
var canvas = document.getElementById('myCanvas');
var ctx = canvas.getContext('2d');
ctx.moveTo(0, 0);
ctx.bezierCurveTo(100, 0, 0, 50, 0, 0);
ctx.lineWidth = 150;
ctx.strokeStyle = '#0f0';
