Re: [mediacapture-fromelement] The sequence canvas.transferControlToOffscreen() followed by canvas.captureStream() does not appear to be specified (#84)

The closest we get to consistency is Chromium implementation, although the `width` and `height` of HTML `canvas` element is not set to the `width` and `height` of the `OffscreenCanvas` before the next "microtask"

// the width and height of OffscreenCanvas were set in Worker thread
// the below assertions occur in main thread after posting message from Worker
console.assert(canvas.width === width && canvas.height === height, [width, height, canvas.width, canvas.height]); // (index):24 Assertion failed: (4) [499, 259, 300, 150]

Nightly support for `canvas` attribute at `ImageBitmapRenderingContext` is WIP (; include `console.log(ctx.canvas)` at line #17). 

Need to go through all of the tests that ran one by one before posting a comprehensive list of the issues that encountered at Chromium and Nightly, respectively.
