Steps to reproduce

1. Go to any page that uses torchlight, e.g. the homepage itself (https://torchlight.dev/)
2. Find a code block that uses line numbers
3. Select & copy code
4. Paste code into a text editor

Expected results

Code is pasted without extra blank lines.

        RequestReceived::class => [                                     ✅
            ...Octane::prepareApplicationForNextOperation(),            ✅
            ...Octane::prepareApplicationForNextRequest(),              ✅
        ],

Actual results

Code is pasted with one extra blank line after every "real" line.

        RequestReceived::class => [                                     ✅

            ...Octane::prepareApplicationForNextOperation(),            ✅

            ...Octane::prepareApplicationForNextRequest(),              ✅

        ],
