Changes to Front Matter Data are only shown after second "save" while running --serve –incremental mode

[Gr0t3Man]

Operating system

Pop!_OS 22.04 LTS

Eleventy

3.0.0-beta.1

Describe the bug

When running eleventy in --serve –incremental mode the changes mode to the Front Matter Data aren't shown after the first "save" of the file. Only after a second save, the changes are visible in the browser.
I first notices this behavour in 3.0alpha17 and 3.0.0-beta.1 shows the same results.

When running without the –incremental option, the changes are direct visible, after a save.

I have asked in the discord channel if others can reproduce this issue. And others seeing the same problem.

Reproduction steps

Create a file test.njk

title: This a title
text: The first textblock of the page

{{title}}

{{text}}

After starting npx @11ty/eleventy --serve --incremental.

The page shows:

This a title
The first textblock of the page

Step 2:
When i add some text to the frontmatter data to:

title: This a title
text: The first textblock of the page. With a second sentence.

And save the file, the screens still shows the old text.

Step 3:
Making an second change to the frontmatter data to:

---

title: This a title, extra long title!
text: The first textblock of the page. With a second sentence.

And save the file, the screen displays:
This a title
The first textblock of the page. With a second sentence.

Step 4:
Doing a second save (no text changes), the screen displays:
This a title, extra long title!
The first textblock of the page. With a second sentence.

Expected behavior

To display the changes directly in the browser, after saving the file.
