*Specification*
https://github.com/whatwg/html/pull/10904
<https://github.com/whatwg/html/pull/10904>
*Summary*
Add the getContextAttributes interface from
CanvasRenderingContext2D to OffscreenCanvasRenderingContext2D. Its
omission from CanvasRenderingContext2D was accidental.
Add support for willReadFrequently and desynchronized to
OffscreenCanvasRenderingContext2D in the HTML spec. The spec
changes for those features were intended to apply both
to CanvasRenderingContext2D and to
OffscreenCanvasRenderingContext2D. Blink has already shipped
support for these.
Clean up the text of the spec to avoid these sorts of mistakes in
the future, and to streamline future changes.

*Anticipated spec changes*
The altered spec text will be further modified soon to add support

cleaning this up would have been irresponsible.
