JSDOM not properly polyfilling requestAnimationFrame

Description

JSDOM is not properly polyfilling window.requestAnimationFrame for us. This causes problems when we are testing head-ful code in a headless environment (i.e. node).

Note that it will not break headless mode (because headless mode doesn't hit this code). It only breaks headful mode when running in node, which we do for some unit tests (e.g. in samples).

Reproduction steps

1. Revert the shim of requestAnimationFrame I added in chore: shareable release prep blockly-samples#1643
2. Run the tests for the shareable procedures plugin using npm run test
3. Observe the errors
