LLMS_Forms::cascade_visibility_attrs( array[] $blocks, string|null $visibility = null )

Cascade all llms_visibility attributes down into inner blocks.

Description Description

If a parent block has a visibility setting this will apply that visibility to a chlid block if the child block does not have a visibility setting of its own.

Ultimately this ensures that a field block that’s not visible can be marked as "optional" so that form validation can take place.

For example, if a columns block is displayed only to logged out users and it’s child fields are marked as required that means that it’s required only to logged out users and the field becomes "optional" (for validation purposes) to logged in users.
