Image Node not rendering on Firefox

Hi,

Using the latest version of VideoContext and this snippet of code, it looks to me that image rendering is broken on VC.

        const canvas = document.getElementById("canvas");
        const button = document.getElementById("button");
        const vc = new VideoContext(canvas);
        const in1 = vc.image("image.png", 0);
        in1.start(0);
        in1.end(10);
        in1.connect(vc.destination);

This works on Chrome 72 on MacOS and other vendors. However this does fail on Firefox 65 and Firefox Nightly.

Reported warning in the console is

Error: WebGL warning: texImage2D: Alpha-premult and y-flip are deprecated for non-DOM-Element uploads.

It can be traced back to this Bugzilla issue https://bugzilla.mozilla.org/show_bug.cgi?id=1400077

I will probably look into that in the next couple of days

I looked a bit more into this issue. It is definitely an issue around createImageBitmap. I suspect a regression on the Firefox JS VM.

I created an issue on Bugzilla https://bugzilla.mozilla.org/show_bug.cgi?id=1533680

Still awaiting fix from Firefox upstream
