That's probably Chrome doing pre-fetches. I have never reproduced that behavior, but there's nothing we can do about it if it does, that's going to trigger a replay error every time.

Figure out a way to reproduce it and then at least we can understand it. I have no expectation that we could fix it if that’s the cause. We can't do much about broken clients. If it's a replay issue, then you could in theory configure the IdP to ignore replay but that's about all.

I have never experienced this supposed prefetch problem in Chrome in all the years people have been complaining about it, but I don't use it often, only for testing.
