            Bug ID: 210058
           Summary: [Safari]When video is hidden, after entering and
                    exiting fullscreen at the end of the playback the
                    video doesn't replay to start
           Product: WebKit
           Version: Safari 13
          Hardware: Unspecified
                OS: macOS 10.15
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: roy.bregman at kaltura.com

I attached an example to reproduce.
This bug happens in Safari (tested in MAC)
* Video should be hidden (display: none)
* Play the video (HLS)
* Enter full screen
* Exit full screen
* Seek to end of playback
* When playing the video the video is expected to start over from currentTime 0. Instead the playback plays the last second of the playback.

This is the example (Try few times as this doesn't reproduce 100% of the attempts):

<!DOCTYPE html>
<html lang="en">
<head>
  <script>
    setInterval(()=>{document.getElementById("currTime").innerHTML = document.getElementById('vid').currentTime}, 500)
  </script>

</head>
<body>
<div id="videoContainer" style="width: 640px; height: 480px">
  <div>
    <video id="vid" src='http://qa-apache-php7.dev.kaltura.com/p/1091/sp/109100/playManifest/entryId/0_xjjki1id/protocol/http/format/applehttp/flavorIds/0_jpggin3q,0_8e75zdb1,0_8bdtuqj2,0_v3u9vh5n/a.m3u8?playSessionId=bf508128-58ae-9cc1-2c88-93751b645189:1a994be0-18d0-6afe-aabe-d42507e84500&referrer=aHR0cDovL2xvY2FsaG9zdDo4MDgwLw==&clientTag=html5:v0.53.0' playsinline controls style="display: none;"/>
  </div>
  <span id="currTime"></span>
  <button onclick="document.getElementById('vid').play()">play</button>
  <button onclick="document.getElementById('vid').currentTime = document.getElementById('vid').duration">seek to end</button>
  <button onclick="document.getElementById('videoContainer').webkitRequestFullScreen();">fullscreen</button>
  <button onclick="document.webkitExitFullscreen();">Exit fullscreen</button>
</div>

</body>
