            Bug ID: 228317
           Summary: Permissions for Camera expires after some time
           Product: WebKit
           Version: Safari 14
          Hardware: iPhone / iPad
                OS: iOS 14
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebRTC

I've a case where I fetch HTML from the backend and load it in WKWebView. It ask's me for camera permission for the URL I set. This HTML also fetches a quite big script, so it's expensive operation. After that I don't kill the View Controller, only dismiss it, so when user open it again, HTML is still loaded and ready. However, after some time with camera activated (I'm throwing a track's stream as a source for <video /> element) it just stops working - preview disappears. When I try to hit navigator.mediaDevices.getUserMedia() again, it just not resolve and quits script with no error. Is it intended? 

Also, Is is even possible to keep the permission after granting it once? App has camera permission, but WebView asks for it every time I init it
