More Modal Not Updating Page State w/ Groups

[ShadeWyrm]

When using the "More" modal for Form Elements, the properties are updated in the template store, but the page state doesn't update.

This means the cypress test (in formbuilder.cy.ts):
cy.get("#required-1-id").should("be.checked");
fails, because while the value was set in the template store, the UI never updates the required checkbox on the main page.

The issue was found when reviewing PR : #3853 (and is related, but not caused by it)
