Reproduction repository

Compile in docker using cli with watch without a tty

Describe your issue

A recent update made changes to detect if there is a stdin or not when watching. With docker, there is no stdin when using something like docker-compose up. The process exits with code 0.

For now, I am going back to 2.2.7. I might be able to spoof stdin for my container. Still working on that.

Here is the code that is causing the issue.

Adding tty to docker compose file for the service fixed the issue. I would not consider this a tailwind issue.

It's a simple config to fix and hopefully this saves someone time.
