Directory data file not respected until 11ty server restarted

Operating system

Linux Ubuntu 22.04.5

Eleventy

3.0.0

Describe the bug

I'm following along with "6 Minutes to Build a Blog from Scratch with Eleventy," although using version 3 instead of 2. When I get to the step to create a directory data file, "posts.json" it does not re-render my post files using the new layout specified. The 11ty logs indicate the files are re-written, but they are unchanged.

I need to restart 11ty then the files are updated using the specified layout. I've also tested this with the permalink property. It is also not respected until I restart 11ty.

Reproduction steps

1. npx @11ty/eleventy --serve
2. Create an index file, layout file, and a subdirectory with content that isn't yet using the layout file.
3. Create a directory data file to specify that subdirectory should use the layout file.
4. Note the pages are not re-rendered with the layout file.

Or follow along to "6 Minutes to Build a Blog from Scratch with Eleventy" until 3:14.

Expected behavior

Files are re-rendered using the layout specified in the directory data file (as well as other options) without having to restart 11ty.

Reproduced! Specifically, this happens when a directory data file is newly created (but some internal cache on the template file not picking it up)

Shipping with v3.1.2-beta.3 or newer.
