esc_url() adding http:// to a relative URL to parent directory '../pathname/'

[OrangePixelNath]

esc_url() adds 'http://' when it shouldn't.

Line 4191 wp-includes/formatting.php states

If the URL doesn't appear to contain a scheme, we presume it needs http:// prepended (unless a relative link starting with /, # or ? or a php file).

This is prepending http:// to a relative url to a parent directory i.e. ../path-to-page/

Funtion needs ../ adding to the array or some regex code.

No sorry. I'm new to the system so didn't understand what was next.

No problem! That’s why I checked to be sure :)
