Returning a newline character causes a syntax error in execute script

[poftadeh]

What happened:
The script return '/n' causes an invalid syntax error in Execute Script Sync.

What you expected to happen:
For the endpoint to return \n

How to reproduce it (as minimally and precisely as possible):
Send { script: "return '\n'", args: [] } as the request body to the endpoint.

Anything else we need to know?:
dom.window.eval("return '\n'") also causes this error in plain Jsdom.
