The piece walks through a simple navigation and then a complex overlapping scenario involving preloads, redirects, and race conditions, tracing back to a rewrite of the router's loading system (PR #7805) that fixed a class of bugs caused by conflating cancellation, supersession, publication, and rendering into too few variables. ## Full article daily.dev links to this article rather than hosting it.
