Comment (by soulseekah):

 Does an actual `Location: ...` redirect header happen? Or are you basing
 your assumptions based on a theoretical canonical semi-state that you see
 inside an internal function? I'd like to see this theoretical bug being
 applied, if possible.

 I doubt that you were intentionally just dumping variables inside the
 canonical functions one day and went "Oh, this is weird, why is this
 `$redirect_url` wrong?" No. Something happened and you had to go digging
 into that function. So what exactly happened? How does this state manifest
 itself to a point that one would need to go look at irrelevant canonical
 states? How do you make that redirect actually happen?

 And thank you for your patience. I'm trying to get the full picture here,
 the implications. So far, that redirect doesn't seem to be manifesting
 itself. So in what practical (or even theoretical) scenario would it
 manifest itself?

 Thanks!
