Description

Steps to reproduce:

Observed behavior:

The renderer field is filled with a 0 (Zero), so the example field placeholder is not visible
This means that the renderer function has run on initialization, while it shouldn't
- This feature was introduced in this patch https://gerrit.wikimedia.org/r/c/mediawiki/extensions/WikiLambda/+/1014482 but it's unclear why it's not working in this case

Expected behavior (Acceptance criteria):

On an empty object (Create page), the renderer function should not run on initialization
The field should be empty
The placeholder values (examples from testers) should be visible
