API test failures look real

[Alexey Proskuryakov]

We need to move iOS testers to macOS Catalina and re-test.

[Tim Horton]

Actually I can repro the API test failures locally... so I have more digging to do.

Exciting!

Still need to update host OS in the infrastructure to properly test (even in EWS)...

Since the canvases are drawing the same image, this code can be simplified like this:

    var image = new Image;
    image.src = "resources/exif-orientation-1-ul.jpg";
    image.decode().then(() => {
        const canvases = document.getElementsByTagName('canvas');
        for (let canvas of canvases) {
            canvas.width = image.width;
            canvas.height = image.height;
            let context = canvas.getContext("2d");
            context.drawImage(image, 0, 0, canvas.width, canvas.height);
        }
        if (window.testRunner)
            window.testRunner.notifyDone();
    });

uint8_t?

or Uint8ClampedArray::tryCreateUninitialized?

document.querySelectorAll("canvas").forEach(canvas => {
  // draw
