Do you know exactly why they are being bumped? Check the debugging logs
if you do not.

The dst ACL works on IPs (including, when necessary and allowed, on IPs
obtained from resolved domain names). In a forward-proxy configuration,
those IPs or domains are extracted from the URL. In an ssl_bump context,
that URL comes from the CONNECT request target.

What is the exact CONNECT request URL when your dst ACL is being
evaluated in your ssl_bump test case? Does the ACL match? Attach the
corresponding debugging log snippet.
