"required_if" validation rule does not work with native "published" field

[dadaxr]

Description

I have a use case where some entries must be partially filled by a given X person, but then published by another Y person.

The X person does not have all the information (ie data) to fill all the required fields needed for publishing.

So I tried to make some fields "required" only when trying to "publish" the entry.

but ... this does not work : the rule is not applied and the field is never "required".

However, this work well on classic statamic collections. So it's related to runway.

My guess was "it's because "published" is not a "user defined" field.

I found a workaround :
add a "published" hidden field in the collection blueprint, and then it works !

Steps to reproduce

create a "publishable" runway resource,

add a blueprint for it, with a "test" (text) field having a "required_if:published,true" validation rule,

try to publish ... the validation rule is ignored.
