requestAnimationFrame is not defined in web-worker in Firefox?-CodePudding

I can't find any information why Firefox v91.10.0esr on Windows 10 complains that requestAnimationFrame is not defined:

const worker = new Worker(
               URL.createObjectURL(
               new Blob(
                  ["requestAnimationFrame(() => this.postMessage('requestAnimationFrame in web-worker process'))"]
                  , { type: "text/javascript" })));

worker.addEventListener("message", e =>
{
  console.log(e.data);
});


requestAnimationFrame(() => console.log("requestAnimationFrame in main process"));

19:09:53.100 ReferenceError: requestAnimationFrame is not defined 569ddce0-b6c3-47c9-88b4-89d59445b335:1:1
    <anonymous> blob:null/569ddce0-b6c3-47c9-88b4-89d59445b335:1

It works fine on Android Firefox and other browsers (Edge, Chrome).

Any ideas?

CodePudding user response：

Firefox added support for requestAnimationFrame and cancelAnimationFrame in workers with v97 as you can see on this issue. Comment 17 and 18 just confirm it.
