[Bug]: "Get browser-compatible JavaScript out" Scrollbar Not working

### 💻

- [ ] Would you like to work on a fix?

### Description
While i was trying to get the browser compatible javascript output, I found out that i am unable to scroll the output that you can see in the below image.

### Current Behavior

Go babel [website](https://babeljs.io/), write some code in `Put in next-gen JavaScript` such that the output width should be greater than the `Get browser-compatible JavaScript out
display width`


### Expected behavior

One should be able to scroll in x-direction

Reproduce the issue on the Babel website by entering JavaScript that produces output wider than the output display. Inspect the output display's frontend implementation and verify that horizontal scrolling works for wide generated code without disrupting the page layout.
