Sandpack v2 CRA template example log babel console warnings

[nirtamir2]

Hi
I'm using Sandpack 2 with CRA example with TS.
When I open my console - I see a lot of warnings

babel.7.20.13.min.js:14 Though the "loose" option was set to "false" in your @babel/preset-env config, it will not be used for @babel/plugin-proposal-private-property-in-object since the "loose" mode option was set to "true" for @babel/plugin-proposal-class-properties.
The "loose" option must be the same for @babel/plugin-proposal-class-properties, @babel/plugin-proposal-private-methods and @babel/plugin-proposal-private-property-in-object (when they are enabled): you can silence this warning by explicitly adding
	["@babel/plugin-proposal-private-property-in-object", { "loose": true }]
to the "plugins" section of your Babel config.

Here is a reproduction

They only show in CRA template (the vite template does not have this problem).

You can see the warnings also in the official docs website when choosing react https://sandpack.codesandbox.io/docs/quickstart#preview

How to get rid of them?
