Comment:

 In [changeset:"60496" 60496]:
 {{{
 #!CommitTicketReference repository="" revision="60496"
 Canonical: prevent possible "Undefined array key" PHP error in
 `redirect_canonical()`, if the `path` or `query` array keys have gone
 missing.

 This commit checks for the existence of (and re-adds if necessary) the
 `path` and `query` array keys after the `$redirect` variable has
 potentially been replaced by a second call to `parse_url()`.

 This may happen when redirecting back to the root domain, without any path
 ('/example/`) or query (`?example=1`) to parse.

 Props chrismattix, dhruvang21.

 Fixes #63733.
