Trying to upload the attached PNG file results in an error message "The file is a corrupt or otherwise unreadable ZIP file. It cannot be properly checked for security." Checking it in a hex editor, it turns out that one of the magic numbers for the ZIP format, PK\x05\x06, appears at offset 0xFA4. Can this be fixed? (If not, the error message should at least be clarified.)
Reminds me of T68428: MimeMagic: ZIP types not properly detected (though MimeMagic is now MimeAnalyzer).
Code that checks for PK\x05\x06 is at https://phabricator.wikimedia.org/source/mediawiki/browse/master/includes/libs/mime/MimeAnalyzer.php$808 and https://phabricator.wikimedia.org/source/mediawiki/browse/master/includes/utils/ZipDirectoryReader.php$221
