Issue Summary

This is reproducible on Data Center: n/a

Steps to Reproduce

1. Go to code diff on any pull request
2. Highlight multiple lines of code and copy to clipboard (Mac: Cmd+C)
3. Paste clipboard content (code block in comment, IDE, ...etc)

Expected Results

Code block is pasted in the same format it was copied in.

Example: 

const test = (x) => {    
    console.log(x);    
    return `x equals: ${x}`;
}

Actual Results

There is an extra line in between every line of code.

Example:

const test = (x) => { 

    console.log(x); 

    return `x equals: ${x}`;

}

Workaround

Currently there is no known workaround for this behavior. User has to manually edit the code block to remove the extra lines.
