 Since upgrading to WordPress 5.5, I am no longer able to set a feature
 image.

 I've tried this on different sites which run on completely different
 hosting servers, always the same issue.

 As you can see from the screen shot, the "set feature image" button simply
 remains inactive.

 Also, the usual image information on the right, once an image has been
 selected, is missing.
