[guest271314]

Attachment: FirefoxImageBitmapRenderingContextWebidlDoesNotDefineCanvasAttribute.html

User Agent: Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.36 (KHTML, like Gecko) Ubuntu Chromium/80.0.3983.2 Chrome/80.0.3983.2 Safari/537.36

Steps to reproduce:

At about:config set gfx.offscreen.enabled to true.

Create HTML canvas element and OffscreenCanvas instances.

For canvas execute transferControlToOffscreen(). Set OffscreenCanvas context to ImageBitmapRenderingContext.

Actual results:

ImageBitmapRenderingContext canvas attribute is undefined at Firefox 70, Nightly 73.

Expected results:

ImageBitmapRenderingContext should have canvas attribute set to HTMLCanvasElement or OffscreenCanvas.

interface ImageBitmapRenderingContext {
readonly attribute (HTMLCanvasElement or OffscreenCanvas) canvas;
void transferFromImageBitmap(ImageBitmap? bitmap);
};
