In case someone is still looking for a solution for this, the following plugin does the job http://mohammadyounes.github.io/jquery-scrollLock/
It fully addresses the issue of locking mouse wheel scroll inside a given container, preventing it from propagating to parent element.
It does not change wheel scrolling speed, user experience will not be affected. and you get the same behavior regardless of the OS mouse wheel vertical scrolling speed (On Windows it can be set to one screen or one line up to 100 lines per notch).
