* 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.
* @param keySystem - The key system in use.
* @returns {boolean}
