Default option (isDefault) for radio buttons and check boxes is not respected by renderForm()

[svale]

Describe the bug

I have an issue where I have a form with a set of check boxes and a group of radio buttons and both should be rendered with a default option pre-selected. While this works nicely in the CP preview, I can not get the inputs to have a preset value checked in the frontend templates. I am using craft.formie.renderForm() to render the form.

Steps to reproduce

1. Create Formie form with either check boxes and/or radio buttons
2. Mark a single option as "Default" in the fields options table in form field edit view
3. Render the form in a template using craft.formie.renderForm()

Form settings

• Multi-page form: No
• Submission Method: Ajax
• Client-side Validation: Yes
• Custom Form Templates: No

Craft CMS version

Craft 5.2

Plugin version

3.0.0-beta.14

Multi-site?

No

Additional context

I have tested this in a local ddev environment and craft cloud, with craft 5.1 and 5.2 and with and without a custom themeConfig passed to the renderForm() method. Hopefully I have just missed some obvious instruction in the docs (but I have really looked...)

Actually, I had missed the part in the docs about Populating Forms and craft.formie.populateFormValues()....

Fixed for the next release. To get this early, run composer require verbb/formie:"dev-craft-5 as 3.0.0-beta.14".
