Apparently IE will report random mime type if there's more then 1 in the list.
So we get the whole list and just use the first one (top priority one)

This behavior belongs in a comment, since it's certainly not in Microsoft's
documentation. It'll be effectively lost if it's only in review comments.

     {
-      mimeType.SetString(mime);
+      mimeType.SetString(mime[0]);
