Flash Messages Failing to Close in New Phoenix Project

The user cakekid9 is encountering a problem with a newly created Phoenix project. Despite successful user authentication functions like register, login, and logout working, the user notices that flash messages do not close upon clicking them. Cakekid9 has attempted to recreate the project from scratch to ensure it wasn't a one-off error, but the issue persists. The user is considering reporting this as a bug but is first seeking insight into whether something might have been overlooked during the setup process. The versions specified are Phoenix 1.7.12 and Elixir 1.16.2, and the issue was consistent across different browsers, like Chrome and Firefox.
