When adding an url for the cache on assets.yaml, from:

image_manipulation_route: '/cache' to image_manipulation_route: 'https://example.com/cache', the template still resolves with a slash:

/https://example.com/cache/blahblahblah

which makes the browser think it is the domain that it loaded the page and doesn't find the image (it is generated because image_manipulation_cached_path has no problem finding the folder. Is there any way i can remove that slash so it generates a proper domain address for my cached images?
