calling play() on <audio> with src from Blob returns Promise that never resolves

Calling play() on an audio tag with src set to a Blob URL returns a Promise that never completes. This looks like a regression after upgrading to Samsung Internet 8.2, from what we can tell.

<audio src="" />

<script>
  function handler() {
    var el = document.querySelector("audio");
    el.load();

    fetch("https://archive.org/download/testmp3testfile/mpthreetest.mp3", {
      method: "get",
    }).then(function (response) {
      return response.blob();
    }).then(function (blob) {
      el.src = URL.createObjectURL(blob);
      return el.play();
    }).then(function () {
      console.log("never resolves");
    }).catch(function (err) {
      console.log("never rejects");
    });
  }

  document.body.addEventListener("click", handler);
</script>
