Comment:

 In 53475.3.diff: Fix this similarly to how `.heic` images are handled, see
 [48288]. Prevents uploading of WebP images when the server cannot edit
 them by passing a setting to Plupload, then triggering an error.

 That also allows to show a better error message (suggestions for improving
 the text are welcome):

  This image cannot be post-processed by the web server. Convert it to JPEG
 or PNG before uploading.

 Please test asap to be able to add in beta-4.
