In WP::parse_request(), $error is set to '404' on line 167 and is not changed again before the '404' === $error check that clears it once a rewrite rule matches. The check therefore always passes and is removed. There is no change in behavior.

This resolves one error in the identical.alwaysTrue PHPStan baseline.

… in `WP::parse_request()`.

When rewrite rules exist, `$error` is set to `'404'` and only cleared once a rule matches. At the point where a matched rule's query is parsed, `$error` therefore always still holds `'404'`, so the `'404' === $error` check around clearing it always passes and is removed.

This resolves one error in the `identical.alwaysTrue` PHPStan baseline.

See #65817.
