A smart back button

A page-supplied "back" button can take you back, even after reload, by inspecting the previous history entries:

backButtonEl.addEventListener("click", () => {
  if (
    navigation.entries()[navigation.currentEntry.index - 1]?.url ===
    "/product-listing"
  ) {
    navigation.back();
  } else {
    // If the user arrived here in some other way
    // e.g. by typing the URL directly:
    navigation.navigate("/product-listing", { history: "replace" });
  }
});
