Comment (by cypherpunks):

 I think this is a pretty nasty issue, especially now that a lot of sites
 are doing this.

 Another way to test this is to use the demo site
 https://perfectoid.space/test.php mentioned in #27502. Nearly every time
 it is reloaded, the entire circuit path changes. This is not unique to
 Cloudflare.
