Would anyone object to changing the output mime type of ApiFormatJson.php from "application/json" to 'text/javascript' ? committed in r55084
This is needed for iframe target background upload tasks. ie you upload a file and then you want to take the name of the file you uploaded and use that to insert the image into the edit window. With mime as "application/json" the browser promts the user to "save" the file and we can't eval the document text result in the iframe.
A good suggestion I read at http://simonwillison.net/2009/Feb/6/json/#c43376 is to use text/javascript only for &format=json when a callback is used, and use application/json when it's not (&format=jsonfm uses text/html in all cases, of course).
