On top of everything you mentioned, TreasuryDirect also has an insanely aggravating issue where if you click a navigation button twice (e.g clicking next again reflexively before the next page has fully loaded), it displays an error about invalid navigation and forces you to login again and start from the beginning.
Even something as simple as disabling navigation links/buttons after being clicked before the next page load would mostly solve this and save hours of frustration having to re-login through their god awful signin flow every time.
