We discussed about ?std::vector.push_back working but ?vector.push_back not working. And ?std::vector and ?vector working.

This is not something that I can change. The format of cppreference-doxygen-web.tag file is such that it has 2 instances for vector. One is std::vector as class and another one is vector as file. Therefore one can find documentation related to both of them. But for any class member function or variable, it can be only access via class std::vector. Therefore the above specified scenario takes place.

I think this is how it is supposed to work.

PR is complete from my side.
