This is off topic and I understand we’re not supposed to comment on such things, but was anyone else mystified by the decisions that went into the scroll progress bar up top (on mobile)? It seems to be two part, where part of it would accurately reflect your scroll state, while the other had some weird latency associated with it. And then it ended up hidden behind the top of page blur unless you scrolled very aggressively, to the point where the blur could not keep up.
