Line indents not displaying in code blocks

Description
When rendering a standard HTML page, any indentation in the code block is removed, and the entire code segment is displayed with the same column index.

In Essence, I expect:

fn main() {
    println!("Hello, World!");
    if(true) {
        println!("It is me!");
    }
}

But I'm getting

fn main() {
println!("Hello, World!");
if(true) {
println!("It is me!");
}
}

To Reproduce
Copy the sample at the end into a raw html file and open it in your browser.

Expected behavior
The code block should preserve formatting, including indentation.

Desktop:

  • OS: Windows 11
  • Browser: Edge, Firefox
  • Version: Edge 98.0.1108.62, Firefox 97.0.1
  • highlight.js version: 11.4.0

Additional context
Presumably, by putting <code> segments into a HTML table, it is removing whitespace.
I've edited my code blocks to replace any double spaces with &emsp;, but this is not optimal for copying code back out.

Thanks for the report!

Try to use full described HTML page with <!DOCTYPE html> & <html>.

The example above works in any browser:

Oh wow I feel like such a noob 🤣
Can you tell I'm usually a backend developer? :p
