As far as I can tell, we're doing what the website is asking us to?

The website has several frames (or the same origin) which serve the `Clear-Site-Data: *` HTTP header. As per the specification, '*' includes 'executionContexts`, which asks the user agent to reload all frames from this origin.

So you have frame A and frame B from the same origin, they each serve `Clear-Site-Data: *` HTTP header, causing each other to get reloaded. Upon reload, they serve the exact same header, rinse and repeat.

I'm looking at the specification but it's not clear to me yet what we're supposed to do to avoid infinite reloads in this case.
