How can React be so great if Facebook's own UI sucks. They can't even get the back button to work correctly.

i think the back button behavior is intentional - at least on mobile.

if someone sends you a link to a piece of content on FB and then you use the back button it sends you to your feed, and now they have a much greater chance of trapping the dear user in their algoverse.
