RegisterEditorComponent (custom widget) FIELDS - Required not working

[isabellaslv]

Describe the bug The 'required' and 'pattern' for custom widgets is not working. It shouldn't allow to save the updates if all required fields are not filled.

To Reproduce

1. Create a custom widget using CMS.registerEditorComponent
2. Set a field as required: true
3. Insert the widget inside the markdown and don't fill the required field
4. Save the updates

window.CMS.registerEditorComponent({ id: 'collection', label: 'Collection', collapsed: true, fields: [ { label: 'Cards', name: 'cards', widget: 'list', fields: [ { label: 'Title', name: 'title', widget: 'string', required: true, }, ]

Expected behavior Won't allow save the updates since the field is mandatory.
