Uncaught ReferenceError: cp is not defined

is it possible to find the implemention of the cp which function declared in types-internal.d.ts?

Overview.

I am getting an error with this package when trying to make use of it in a codemirror project.

I'm a newbie to codemirror, and just a dabbler not a full time programmer so bear with me.

The error for me can be produced as easily as the following:

Steps to reproduce.

1. Create a new project with npm init.

2. Install codemirror and rollup/@rollup-plugin-node-resolve along with this project: npm install codemirror lang-tex rollup @rollup/plugin-node-resolve.

3. Create a javascript module that loads the package. I can get the problem with something as simple as this:

import {EditorView, basicSetup} from "codemirror";
import {texSyntax} from "lang-tex";

let editor = new EditorView({
    extensions: [basicSetup, texSyntax()],
    parent: document.body
});

export default editor;

4. Try to use rollup to bundle the dependencies needed for codemirror with this extension, using node_modules/.bin/rollup editor.mjs -f iife -o editor.bundle.js -p @rollup/plugin-node-resolve as suggested here.

When I do so I get this output:

editor.mjs → editor.bundle.js...
(!) "this" has been rewritten to "undefined"
https://rollupjs.org/troubleshooting/#error-this-is-undefined
node_modules/lang-tex/lib/index.js

2: var __createBinding = (this && this.__createBinding) || (Object.create ? (function(o, m, k, k2) {
                          ^
3:     if (k2 === undefined) k2 = k;
4:     Object.defineProperty(o, k2, { enumerable: true, get: function() { return m[k]; } });
...and 3 other occurrences

    at ObjectExpression.bind (/home/frabjous/tmp/textest/node_modules/rollup/dist/shared/rollup.js:7359:28)

The expected behavior is that I not get this error, and that I be able to use the extension in a simple codemirror instance.

It's possible I just didn't install things right. Again, newbie.

Versions

• codemirror v 6.0.1
• lang-tex 0.0.3
• @rollup/plugin-node-resolve 15.1.0
• rollup 3.26.2

I did get a lot of deprecation warnings about lezer packages when installing lang-tex, which may or may not be relevant.

Note I posted about this in the codemirror discussion forum here but didn't get any replies.

Describe the bug
When I enter "\" at an Editor that inits with blank content, the browser would pop up this error. However, If enter some other keys first, then enter "\", everything is going completely correct.
