Why copy function is not working inside setTimeout?

Inspired by the mention of with in this answer, I discovered that you can use it to make copy() available in setTimeout() and other callbacks, instead of having to create a global reference to it:

with ({ copy }) { setTimeout(() => copy("copied!"), 0) }

copied! will now be on your clipboard. Unfortunately, this trick doesn't seem to work in Firefox's console.

copy is part of the developer tools' Command Line API and is not available outside the browser console. For example, trying to execute the command in a JavaScript file that's part of a normal web page you'd get the same error.

When you invoke the command inside the setTimeout callback, the execution context is no longer the console so copy doesn't exist anymore.
