 Hi there,

 I was just wondering if anything has changed regarding
 https://developer.wordpress.org/reference/functions/redirect_canonical/?

 `https://some-domain.tld/?my_param=a+a`

 triggers a 301 redirect to
 `https://some-domain.tld/?my_param=a a`

 Now our CDN is set to pass URLs with `my_param` straight on to WordPress.
 Since that response with a 301, that's what gets cached by the CDN and
 causes a redirect loop.

 Is that something new? I hadn't had that issue before, but also not 100%
 sure if I sent a value like "a+a" before. Trying to figure out why this
 redirect loop happens now after years.

 I'll leave that ticket to be a bug, but if nothing has changed in
 redirect_canonical() then I guess it can just be closed.

 Thanks for your help.
