I stand corrected wrt the operators; while the diagram mentions that there is an ingress and egress component, it is not clear as to whether two different entities operate them. I've updated my comments to reflect that. Iff they're the same operator, I assume there'd be a TLS connection between Microsoft Edge Secure and the Edge browser, and that'd be a long-lived session because of the nature of proxying traffic, which means there's a static identifier. Even if it wasn't, IP addresses may themselves be considered as sensitive enough for such identification.
