Form checkboxes with required

[AtmoFX]

Bug description

Continuation to the recent, unanswered discussion: #10984

When adding the validation required to a Checkboxes field, the form cannot be submitted unless all the options are ticked. I cannot find a way to validate a checkboxes field so that the submission is accepted so long as I check at least 1 entry but not all of them.
The important thing pointed out by @stephenmeehanuk is that the behavior disappears when the hidden field is removed.

The reason I classify this issue as bug is because the behavior was apparently introduced by: #7180. It must have worked before.

How to reproduce

Create a form with checkboxes containing more than 1 option.
