I dunno - I don't think you're gonna win that battle. When a library is sufficiently advanced it often becomes a distinct entity (linguistically, at least) from whatever it's built upon.
See also: React, Pandas, Numpy, Boost, etc.
It might be confusing to those without the context to understand that e.g. React is built on vanilla JS, but I think it's pretty clear to most people that jQuery is built on JavaScript.
In fact the term "vanilla JS" mostly started in response to jQuery itself, so if anything I would argue that the term "vanilla JS" is to blame for what you're talking about.
