/**
 * This functions tells if the RxPlayer can trust the browser when it has
 * successfully granted the MediaKeySystemAccess with
 * `navigator.requestMediaKeySystemAccess(keySystem)` function, or if it should do
 * some additional testing to confirm that the `keySystem` is supported on the device.
 *
 * This behavior has been experienced on the following device:
 *
 * On a Microsoft Surface with Edge v.124:
 * - Althought `requestMediaKeySystemAccess` resolve correctly with the keySystem
 *   "com.microsoft.playready.recommendation.3000", generating a request with
 *   `generateRequest` throws an error: "NotSupportedError: Failed to execute
 *   'generateRequest' on 'MediaKeySession': Failed to create MF PR CdmSession".
 *   In this particular case, the work-around was to consider recommendation.3000 as not supported
 *   and try another keySystem.
 *
 * - On Firefox v.137:
 *   Similar issue with requestMediaKeySystemAccess that resolves correctly with
 *   'com.microsoft.playready.recommendation.3000' but fail at the `createMediaKeys``
 *   step with error `WMFCDMProxy: Init: WMFCDM init error`
 *
 * @param keySystem - The key system in use.
 * @returns {boolean}
