Creating a Checkbox or Modal emits an error in the console when using Preact

Steps

1. Using the preact-cli, build a basic project.
2. npm install --save semantic-ui-react
3. Add a simple form with a checkbox element anywhere in the project. Sample code:

<Form>
    <Form.Checkbox label='Why the errors?'/>
</Form>

1. The following errors show up in the console log.
   1. Checkbox is missing "defaultChecked" propTypes validation for auto controlled prop "checked".
   2. Checkbox is missing propTypes validation for auto controlled prop "checked".
   3. Checkbox is missing "defaultIndeterminate" propTypes validation for auto controlled prop "indeterminate".
   4. Checkbox is missing propTypes validation for auto controlled prop "indeterminate".

Expected Result

No errors are emitted.

Actual Result

4 errors are emitted.

Version

0.71.1

Testcase

Repository is pretty barebones, but had to make a separate project in order to demonstrate the issue. https://github.com/rbscott/auto-controlled-error

Notes

I am not sure if Preact is official supported, but it seems to mostly work. If someone points me in the right direction, I could put together a Pull Request.

@levithomason thanks for the info. It looks like preact removes prop types for all builds. There is a PR to change this behavior so it only removes propTypes during production builds. I believe this will resolve this issue.

@rbscott preact-compat is the solution you are looking for.
