Hide expression on repeat component breaks defaultValues of nested fields

[gaetanlgce]

Description
When using expressions.hide on a custom repeating section to conditionnally display it, defaultValue is ignored in fields in the fieldGroup. If the expressions.hide is not present, default values are applied as expected when adding items.

Minimal Reproduction
https://stackblitz.com/edit/angular-e9plpt?file=src%2Fapp%2Fapp.component.ts,src%2Fapp%2Frepeat-section.type.ts,src%2Fstyles.scss,src%2Fapp%2Fapp.component.html

In this example, the defaultValue: 'Buy eggs', is not applied as expected because there is the hide expression line 46.

Your Environment

• Angular version: 14.3.0
• Formly version: 6.3.0

Additional context
It's maybe related to that issue #2651

Hello @aitboudad , Thanks for looking in to this bug.

In our case, We are facing slightly diff issue..We have Json schema, in which we are applying some patches, which contains hide expression on some fields
for example: below fields are wrap inside an type = array field with minItems:1

bitrate: { expressions: { hide: (field: FormlyFieldConfig | undefined) => { return false; } } }, definition: { expressions: { hide: (field: FormlyFieldConfig | undefined) => { return false; } } }

In schema these fields have defaultValue as well.

But when form renders initially, fields which contains hide expression their default value gets overridden in someway and those fields does not appear in main model (Hence empty fields renders even those have defaultValues). if we add new items in array those hidden fields appear with their defaultValue.

So I am not sure what is causing such issue, Do you have any suggestion on what is wrong here ?
