OK.

No, you found a *temporary* *workaround*.

  var field = …

  var t = window.setTimeout(function () {
    field.focus();
    window.clearTimeout(t);
    field = null;
    t = null;
  }, 50);

That is, of course, also only a temporary workaround.

implementations instead of browsers.  There are more than three different 
browsers anyway.
