Description Philip Jägenstedt 2022-08-19 01:42:47 PDT 
This was specified in HTML here:
https://github.com/whatwg/html/pull/6764

It was implemented in Firefox 28 and in Chrome 99.

There are some tests:
https://wpt.fyi/results/html/canvas/element/manual/context-attributes/getContextAttributes.html
https://wpt.fyi/results/html/semantics/embedded-content/the-canvas-element/2d-getcontext-options.html

Unfortunately, those tests look a bit broken to me, and aren't actually testing if willReadFrequently works.
