Applies #24144 to the equivalent matches of generic types, and adds the behavior to matches of generic invocations to generic invocations. Not encountered in many cases so it's hard to come up with tests but an example is the test code in #24688, the match to the generic body never sets the inheritance penalty leaving it at -1, but the match to the generic invocation sets it to 0 which matches worse, when it should set it to -1 because the object does not participate in inheritance.
