I stumbled upon this when creating the tool for the docs 👍 https://github.com/contao/docs/blob/4e99fef22a8076bbdea1a8cc6caee7e01b3459a2/page/static/js/tools.js#L10

Should be this on the JS side: (check the double escaping at the end)

- ^([^:]+)://(([^:@]+)(:([^@]+))?@)?([^:/]+(:[0-9]+)?)/([^?]+)(\?.+)?$
+ ^([^:]+)://(([^:@]+)(:([^@]+))?@)?([^:/]+(:[0-9]+)?)/([^?]+)(\\?.+)?$
