Hi everyone. Hope you're well.

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and couldn’t find anything (or linked relevant results below)

Affected packages and versions

This pertains to the playground, so whatever package/version is in use there.

Link to runnable example

See below.

Steps to reproduce

Probably the rendering engine and the OS don't matter, but I tried both Firefox and Chrome (latest versions) on macOS, on Intel, running Catalina.

1. visit https://mdxjs.com/playground/
2. select {{padding: '1rem', backgroundColor: 'violet'}} with the pointing device (or your finger)
3. overwrite the selection by typing "

Expected behavior

I'm probably not going to get the terminology right here, since JSX and all this is new to me, but I am trying this out because I think I might have a use case for it.

The first thing I wondered about with the playground demo is "how is this different from CSS?" so I tried replacing the object within the JSX variable—the {{stuff in braces}}—with a quoted attribute, plain CSS. This is when I experienced the crash.

Actual behavior

The entire page goes white. The following error messages appear in the developer console:

Error: Minified React error #62; visit https://reactjs.org/docs/error-decoder.html?invariant=62 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.
    React 8
react-dom.production.min.js:193:243

Uncaught Error: Minified React error #62; visit https://reactjs.org/docs/error-decoder.html?invariant=62 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.
    React 8
react-dom.production.min.js:50:340

Runtime, Package manager, OS, Build and bundle tools

As noted above, this was Firefox and Chrome on macOS, but I think that probably doesn't matter. The issue pertains to the web site, specifically the playground.

Thanks!
