Hi guys, Is it possible on webOS with chromium 68 and above to make DRM playback with persistentState set to 'required'? I'm testing with command: 'navigator.requestMediaKeySystemAccess('com.widevine.alpha',[{videoCapabilities: [{robustness: 'SW_SECURE_CRYPTO', contentType: 'video/mp4;codecs="avc1.42C015"'}], persistentState: 'required' }])' and on LG tv got "DOMException: Unsupported keySystem or supportedConfigurations."
