We do not want to commit WKTR metadata such as `<!-- webkit-test-runner [ AsyncOverflowScrollingEnabled=true ] -->` to upstream WPT files, but the unanimous understanding is that we want the test runner to run WPTs with async overflow scrolling enabled. We should hardcode enablement of this web preference feature when the test runner is running WPTs.
