Timeline Editor: Moment description changes do not appear until the editor/project is closed and reopened

[iampremo]

In the Timeline Editor, typing in a ///@desc or @///description for a moment does not show this in the list until the Timeline Editor is closed and reopened:

After closing and reopening the timeline itself (not just the code editor for the moment):

Cutting and pasting a Moment into another will cause the same issue - doesn't matter whether you actually do this via the moments list in the editor panel. or via selecting all code and copy/pasting that.

And the "Duplicate" command also gives the same results.

Note also that if the timeline editor is left open when closing the project, then reloading that project will also show the issue until you close-and-reopen the editor once more.

Steps To Reproduce

1. Start GMS2 and open/create a project
2. Create a Timeline
3. Add a moment
4. Add a ///@desc line at the top
5. Wait and observe the description never appears in the editor window
6. Close and reopen the timeline
7. Observe the description now appears
8. Duplicate that Moment and observe the new one's description is not set
9. Add a third Moment, then copy the first Moment and paste it onto the new one, and observe the new one's description is not set
10. Add a fourth Moment and this time use Ctrl+A, Ctrl+C, Ctrl+V to copy/paste the code only between the two moments, and observe the new one's description is not set

This is a very old report, but as the new linked issue above and my substantial update to the issue show, this is all still affecting 2024.800 Betas.
