MimeTypeArray object, which contains a list of
MimeType objects representing the MIME types recognized and supported by the browser. The array can be queried for information about the enabled plugin that is used to handle a file of the specified type. Named properties of the returned object are not enumerable (except in very old browser versions).
Recent versions of the specification hard-code the returned set of MIME types. If PDF files can be displayed inline then
text/pdf are listed. Otherwise an empty list is returned.
Navigator.pdfViewerEnabled to determine if inline viewing of PDF files is supported. Do not infer it from this property.
Legacy browser versions do not hard-code the list returned by the property, and might return other MIME types.
