NTI vs OTI inconsistency in @record missed property handling

[dmitryxcom]

To repro, compile this with OTI and NTI:

/** @record */
class ChromeWebPushMessage {
  constructor() {
    /** @export {string} */
    this.deviceId;

    /** @export {number} */
    this.timestampSec;

    /** @export {number} */
    this.displayCap;
  }
}

/**
 * @param {!ChromeWebPushMessage} data The payload extracted from the push event.
 * @param {string} url The URL to navigate to if the user clicks the
 *     notification.
 */
function displayNotificationPayload(data, url) {
  if (data.xxy) { // <---------- THIS THING, IS IT WAI NOT TO REPORT MISSING PROPERTY?
    const /** string */ x = data.xxy;
  }
}

OTI reports missing property (expected), while NTI does not.
