Watching input files breaks when listing directories in content

This minimal working example demonstrates a bug present in tailwindcss v3.2.2.

Description

When a pattern with a directory is listed in the content option, the watching of input files ceases to function, unless the input files reside within the same directory.

For instance, in newly generated Phoenix v1.7.5 projects, the input file is assets/css/app.css and the content is set to assets/js/**/*js and lib/my_app_web/...<path to heex files>. Changes to the app.css do not cause the watcher to trigger.

To reproduce this bug

npx tailwindcss --config tailwind-good.config.js --input main.css --output dist.css --watch

# ... make edit to main.css
# ... observe recompilation

npx tailwindcss --config tailwind-bad.config.js --input main.css --output dist.css --watch

# ... make edit to main.css
# ... observe no recompilation

Expected behaviour for both cases: Asset is recompiled when main.css is changed.

To reproduce this repository

Just for reference:

- `npx tailwindcss init`
- Drop standard import directorives in `main.css`
- Create an empty directory called `some-dir`
