You're mistaken. MdN says:

strict-origin-when-cross-origin (default) Send the origin, path, and querystring when performing a same-origin request. For cross-origin requests send the origin (only) when the protocol security level stays same (HTTPS→HTTPS).

So no path is sent to the destination of a link over https - only the domain.

You left out the part which contradicts your claim.

> Don't send the Referer header to less secure destinations (HTTPS→HTTP).

The referer header is still sent from HTTPS to HTTPS.

Yes, but only with the domain not the full path. Does anyone really care that the domain is leaked? There are very few secret domains...
