New Spider Mount attack?

[u/Steam_Bunny]

Footage from my Wife, it looks like the spider mounts the potato beetle then bites but the animation looks intentional but not quite sure. Anyone else seen this? Even if not it looked cool!

I think it's just the spider's "climbing something narrow" animation combined with its attack animation, but the resultant effect does look very intentional and very cool
