And list OffscreenCanvas as member in the CanvasImageSource union type description (it was already part of the IDL).

Fixes #3341.


💥 Error: Wattsi server error 💥

PR Preview failed to build. (Last tried on Jan 15, 2021, 7:58 AM UTC).

PR Preview relies on a number of web services to run. There seems to be an issue with the following one:

🚨 Wattsi Server - Wattsi Server is the web service used to build the WHATWG HTML spec.

Marking "do not merge yet" as there's still some questions surrounding OffscreenCanvas.

@junov so Offscreencanvas itself doesn't seem to really have this bit, only the 2d context for it. How does that work? I guess the 2d context is the bitmap so it works out?

Right... In the case of HTMLCanavasElement, it is actually a shared reference. Context's output bitmap == element's bitmap. We should either define what the "OffscreenCanvas object's bitmap" refers to or change the wording to something like the "OffscreenCanvas object's context's bitmap"
