Automatic update from web-platform-tests Fix a crash in AILanguageDetectorFactory::capabilities() called on a detached frame - Add [RaisesException] EA to AILanguageDetectorFactory::capabilities(), raise an exception when no execution context is present; - See if execution context is available before calling GetLanguageDetectionDriverRemote() - Add a CHECK() within GetLanguageDetectionDriverRemote() to enforce that.
