Sometimes the preload doesn't connect back. And displaying the image is delayed until the preload channel is cancelled with parent-connect-timeout. It looks like this: https://share.firefox.dev/4062ct3
I'm mostly concerned about why this is an intermittent failure./What makes this intermittent.
It looks like the preload loads the image from the image cache in these cases.
I have to verify that the same bug doesn't exist for the other assets.
I have a patch that fixes this by not using the image cache on early hint preloaded requests, but I'm not sure whether that is the correct approach.
The bug only happens when the server response includes a Cache-Control: no-store on the image reply.
