Description:
Mediawiki prevents you from selecting files that are not in the $wgFileExtensions array, even when $wgCheckFileExtensions is set to false. When you select the file, it clears the upload file field.
Expected behaviour: When $wgCheckFileExtensions is set to false, you should be able to select any file.
Occurs in Firefox and Chrome, but not IE.
Version: 1.16.x
Severity: normal
