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.
