**Bug description**  
Custom code components strip the custom code of all newlines. This causes problems. Here are some affected use cases relevant to me:

1. JavaScript using standard `//style` comments. Because newlines are removed, everything after the double slash is registered as a comment.
2. Users are entirely unable to leverage the [`{% liquid %}`](https://shopify.dev/docs/api/liquid/tags/liquid) tag from Shopify’s Liquid language, which (like Python) relies on newlines to distinguish different lines of code.

The issue can lead to frustrating debug sessions and hours of wasted time. I have been working around this since we started using [Builder.io](http://Builder.io) in early 2023. Now, I find that once again our ambitions are slowed by the issue. _Please enable Custom code components to retain their newlines._

**Detailed steps to reproduce the bug**  
Go to the editor, expand the “Code” section and add a `Custom code` component to your page. Update the new component’s code to the following:

```html
<script>
var builderTest = "BEFORE";
// simple comment
var builderTest = "AFTER";
</script>

```

Preview the page and open the dev console. Type `builderTest` and press enter. You’ll see that the variable contains the value “BEFORE” when it should be “AFTER”.
