All schema data lost in case of error

[genvarek]

Prerequisites

• I have read the documentation;
• In the case of a bug report, I understand that providing a SSCCE example is tremendously useful to the maintainers.
• Ideally, I'm providing a sample JSFiddle or a shared playground link demonstrating the issue.

Description

In case of some errors the playground turns into a blank page. It looks like that:

If I click on "go back" in Chrome or reload the page, I return to the default example and my own json schema is lost.

Steps to Reproduce

1. Go to the shared playground https://bit.ly/38Ns83L
2. Try to type in the UI schema inside "case2" this: "ui:widget": "radio"
3. The form is lost!

Expected behavior

Errors are underlined with red curved lines like typos. Or anything else, but I don't want my data to be erased!

Actual behavior

Data is lost.

Version

Current playground

I have the same issue here when users edit UI Schema, and they type word by word and issue happened

This will be fixed in the playground in #3164. To fix this in your own application, I recommend using an error boundary and/or not committing an invalid UI schema to the Form component.
