States API visible stops others states

Problem/Motivation

Discovered during 🐛 After enabling Require Summary on a field can't save the field Needs review

Steps to reproduce

When using

      '#states' => [
        'unchecked' => [
          ':input[name="settings[display_summary]"]' => ['checked' => FALSE],
        ],
        'visible' => [
          ':input[name="settings[display_summary]"]' => ['checked' => TRUE],
        ],

The checkbox appears and disappears fine but is never unchecked.

Proposed resolution

All states should run but solution is TBD

Remaining tasks

User interface changes

API changes

Data model changes
