Why is this left commented out on each update? Or more specifically, this:
$("#aw-whats-new-submit").prop(“disabled”, true).removeClass(‘loading’);
If it’s left commented out, when you try and upload an image without putting any text into the “What’s new?” form, you get a popup. When you dismiss it, the loading spinner remains on the submit button (see attached image).
It seems to me the proper behavior would be to remove the spinner.
