Phoenix 1.7 welcome page assets not showing properly

Turns out this is a bug with the mix task, it simply generates the wrong code for umbrella phoenix apps:

Phoenix app generated in umbrella app (phx.new.web) does not generate correct app.css

### Environment * Elixir version (elixir -v): Elixir 1.14.3 (compiled with Er…lang/OTP 25) * Phoenix version (mix deps): phoenix 1.7.2 * Tailwind version: tailwind 0.2.0 * Operating system: Ubuntu 22.04.2 LTS ### Expected behavior I would expect Phoenix apps generated `phx.new` and `phx.new.web` to display the same. ### Actual behavior Generate a (non-umbrella) Phoenix app: `mix phx.new test --no-ecto` `cd test` `mix phx.server` Produces an `app.css` with 1823 lines and renders correctly. Generate an umbrella app and generate a Phoenix app inside it: `mix new test_umb --umbrella` `cd test_umb/apps` `mix phx.new.web testweb --no-ecto` Add `{Phoenix.PubSub, name: Testweb.PubSub}` to children in `application.ex` `cd .../test_umb` `mix phx.server` Produces an `app.css` with 687 lines and does not render correctly. The first 680 lines of both `app.css` seem to be the same.

With the help of the wonderful people at Elixir’s Discord chat, we raised this ticket.
Hopefully, it will eventually be fixed.

In the meantime, if you are creating a Phoenix umbrella app, you can try the theoretical workaround provided in the ticket created. However, since I am not sure this is the way the Phoenix team is going to go with fixing this, I would personally still wait for their fix, or at least for confirmation they are going to implement it this way.
