Eleventy stops watching for new files (reproducible)

[genemars]

Describe the bug

This is different than #2270 . Eleventy watcher stops watching any newly added files under the following circumstances.

To Reproduce

1. Create a new project as explained in Eleventy docs:
   https://www.11ty.dev/docs/getting-started/

2. Add a test.js file in the root of the new project:

const fs = require('fs');
const mkdirp = require('mkdirp');
const ts = new Date().getTime();
mkdirp.sync('./source/content/blog/post-' + ts);
fs.writeFileSync('./source/content/blog/post-'+ts+'/index.md', 'Hi there!');
if (!fs.existsSync('./source/content/blog/index.liquid')) {
  fs.writeFileSync('./source/content/blog/index.liquid', 'hello');
}

3. Start the dev server:

npx @11ty/eleventy --serve

4. In another terminal run the script for two times (or more)

node test.js

6. Eleventy will build correctly every time the script is run
7. Remove the test folder: rm -rf source/content/blog
8. Run the script again for two times: Eleventy will only rebuild the first time and it will ignore any subsequently added file.

Expected behavior
Should detect new files and rebuild.

Environment:

• OS and Version: Linux
• Eleventy Version 1.0.1 and 2.0.x as well

The test script and steps described above are a simplification of what happens in the following video. After deleting the
blog section, adding it again, only the first post is built.
