Subject of the issue

Great Job on the v2 rc release! Noticed a minor bug with error catching on the new Playground page for the new Javascript expressions support.

Your environment

• OS: Window 10
• Packages: 2.0.0-rc.1 on https://v2.mdxjs.com/playground/
• Env: Chrome

Steps to reproduce

Invalid JSX Errors are caught correctly by the Compile tab:

Hello, world!
Below is an example of markdown in JSX.

</div>

Errors are NOT caught by the Compile tab when when using the new Javascript expressions syntax {...].

Hello, world!
Below is an example of markdown in JSX.

{r}

The page crashes from the error, error from chrome console:

Expected behaviour

Errors within Javascript expressions {...} should caught by the Playground Console tab like JSX syntax error.

Actual behaviour

The page crashes from the error, force you to refresh Playground.
