Summary Non-file inputs cannot be changed to file inputs via JavaScript

Test case: <!doctype html> <script> var el = document.createElement("input"); el.type = "radio"; el.type = "file"; alert(el.type); </script> Chrome dev (on Ubuntu) and Safari 5 (on XP) alert "radio". Recentish Firefox nightly and Opera 10.60 alert "file". The latter is certainly correct per spec. If there's some security reason for this, the spec should be changed to mandate it so we have interoperability.
