It's obvious that "girls do bullying". That was not the question, and it is not even clear whether the original intent in the discussed case was primarily sexual (as in jerk-off template) or primarily harassment or a combination of both. It obviously became harassment, though.
And "girls do bullying" is not at all new, as you claim, and it has nothing to do with your "traditionally male areas", either, that's pure ideology again. You would have seen that already in, like, convent schools for girls in the middle ages.
And then, "we don't talk about toxic femininity" (what we really should define before even talking about it, it isn't widely used in the meaning you seem to give it) is a straight-out ideological lie, as you're proving yourself. Some, like you, try to make stuff like that the subject everywhere they go, even when there's not the slightest reason.
Sexism plus masculism.
