Html containing quotations in label of option values for Checkboxes and Radio buttons break the form

[lachko]

HTML code in the option value of a form's radio button or checkbox option breaks the form

If we add an input as below and then open this input in Edit mode and save. The form is broken and all code moves to an HTML container.

 <tangy-radio-buttons name="contacted_by_school" required="" question-number="12." label="How frequently have you been contacted by any school official or representative (i.e. group leader) (by phone or in person, or by sms, email, FB messenger, group chats and/or other forms of communication) in the last four weeks

We should escape input and then unescape it when presenting prior input. This is true for any place we are taking user input in tangy form editor. There are probably many more places where double quotes can break a form.

Here is the example: https://glitch.com/edit/#!/atlantic-torpid-beluga?path=index.html%3A14%3A15

Open the item, edit the tangy-radio-butons, then save the radio buttons. Notice how markup gets removed.
