Comment (by azaozz):

 I know this is somewhat hard to test/trigger the retry requests. Here's an
 image that may do it:
 https://upload.wikimedia.org/wikipedia/commons/f/ff/Pizigani_1367_Chart_10MB.jpg

 To test: download that image, then drop it in a new "image" block in the
 block editor (make sure the Gutenberg plugin is not installed or is
 disabled), and watch the network tab in the browser tools.

 As this is a "high density" 10MB JPEG image it fails to get post-processed
 on the initial request on my test server, even with the default sub-sizes
 and PHP settings. Alternatively few more large sub-sizes may need to be
 added or the `max_execution_time=30` setting in php.ini may need to be
 reduced for this test.
