Windows 11

Eleventy

4.0.0-alpha.10

Describe the bug

A simple eleventyConfig.setServerOptions({ watch: ['_site/styles.css'] }); for example is perfectly working with the official latest version 3.1.6, it displays a message, and the browser is updated with a new/updated css file built somewhere else. It doesn't do anything in the canary 4.0.0-alpha.10.

You can try to drag/drop or copy styles.css in the provided repo.
