[Marc Leclair [:mleclair]]

(In reply to Valentin Gosu [:valentin] (he/him) from comment #7)

Hi Mark, I hope it's OK if we assign this to you.

Yes, that's fine. I talked with Manuel, and he mentioned two cases:

"1. The test case doesn't use the preloaded object (doesn't display the image) and therefore doesn't wait for the request to complete -> it might go into the next test case.
2. We cancel the early hint request when we get the redirect, but it could already be sent to the server (inherently racy, we can't fix that, we can only allow it to happen)"

It seems that he's also working on a few extra redirect test cases + a cancel notification to stop the EH on redirects. So we should maybe disable this for now?

I'm not sure how to do that though.
