When inspecting YouTube network activity I came across this[1] weird asset being loaded, it show just a single white dash on black. It seems to me like some sort of dicey fingerprinting behavior to see how the image loads.
I've found something similar in the form of a GIF being loaded q.stripe.com on sites that have Stripe enabled, does anyone know the purpose of these and/or why Google uses it only YouTube but not on any of their other services?
I can't even figure out what filetype this is, it's definitely an image of sorts but Windows keeps blocking the download.

EDIT: This is what gets loaded from stripe: https://q.stripe.com/?event=<random string>event_count=<etc>
