Comment (by oliward@…):

 Replying to [ticket:58513 oliward@…]:

 Worth noting this was initially discovered on a multisite installation,
 but also tested on a fresh WP setup, non-multisite, after allowing JSON
 file upload with:


 ```
 add_filter('upload_mimes', function ($mimes) {
     $mimes['json'] = 'text/plain';
     return $mimes;
 });
 ```

 > When uploading a JSON file of exactly 1048577 bytes or less leads to:
 >
 > {filename} has failed to upload.
 > Sorry, you are not allowed to upload this file type.
 >
 > Even though the file type is allowed. Tested with JSON file of valid
 JSON of 1048578 bytes (success) and 1048577 byes (failure).
