            Bug ID: 227169
           Summary: [GStreamer] Seeks on `loadstart` are ignored
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: aboya at igalia.com
                CC: bugs-noreply at webkitgtk.org

Test case:

<!DOCTYPE html>
<html>
<body>
<video src="assets/media-1video-1audio.mp4" id="v" controls></video>
<script>
  v.onloadstart = () => {
    v.currentTime = 5;
  }
</script>
</body>
</html>

Expected: the poster should show t=5, and when clicking on the video it should start playing at t=5.
Actual: the poster shows t=0 and starts playing at t=0.

The multi-platform code is sending the seek, but it's getting lost somehow. It needs investigation.

CONSOLE MEDIA LOG HTMLMediaElement::seek(53011021D81494C6) {"value":5}
CONSOLE MEDIA INFO HTMLMediaElement::seekWithTolerance(53011021D81494C6) time = {"value":5}, negativeTolerance = {"value":0,"numerator":0,"denominator":1,"flags":1}, positiveTolerance = {"value":0,"numerator":0,"denominator":1,"flags":1}
