Importing scripts with the main code

[kuleshov01]

Hello everyone

I want to add the page code via the import button, but when this button is clicked, my <script>code</script> disappears.
What needs to be changed so that the system allows the insertion of <script>

Working example https://github.com/GoodPHP/whitener-preset-grapesjs

And you come out like this:

Disappearing!
