Comment (by andraganescu):

 So the way to stumble upon WordPress not supporting this format is this:

 - shoot a _live_ photo on your phone with at least iOS 11
 - have is synced to your iCloud Photos
 - using a browser (Safari) go to your iCloud and open the cloud Photos
 - open your photo and download using the top bar download button

 This will result in an "iCloud Photos" in the Dowloads folder (at least on
 OSX it will) and in that folder you'll get a heic file and a mov file.

 Attempting to upload this file will not work on stock WordPress.

 Uploading directly to stock WordPress' Media Library will work as Safari
 (tested with Firefox mobile as well) will convert the file to jpeg
 directly on upload.

 Since browsers don't support these formats at all, but users expect them
 to work as normal images I suspect there should be a flow like:

 - user uploads these formats
 - server side we convert to something browsers can display
 - we show the converted (?) file in media library and default attachment
 pages to that
 - we keep (or not?) the original and if we do keep we should link the
 converted file to the original


 That would be smooth and expected. The other option is to simply let these
 files be uploaded.
