Comment (by adamsilverstein):
Hi @Boniu91 thanks for testing this out. A couple of things to check:
* If you are running core from the `build` branch you need to run `grunt
build` after applying the patch.
* Make sure you are uploading a large JPEG image, you should see the img
source code contain references to a bunch of sub-size WebP images sizes as
srcset entries in the image html.
WordPress never changes your original uploaded source image, and I think
your image in your test was small enough that is all it used. So if you
upload a small JPEG, WordPress places that small JPEG. When you upload a
large image though, the re-sizing routines kick in and this is where you
will see the conversion to WebP take place.
