Steps to reproduce this
Calling setAttributes in WebGL mode might end up recreating the underlying canvas and renderer object.
Say you're trying to position the element, e.g. like this:
let canvas = createCanvas(100, 100, sketch.WEBGL);
// ...
canvas.position(0,0);
Unfortunately, this stops working after a setAttributes call, because after that call, canvas !== _renderer. Currently, to fix it, one would have to do:
createCanvas(100, 100, sketch.WEBGL);
setAttributes({ alpha: true });
let canvas = _renderer;
// ...
canvas.position(0,0);
