[Bug]: Playwright CT 1.43.1 throws Vite/Rollup error when testing MUI

[PanchoutNathan]

Version

1.43.1

Steps to reproduce

import { test } from "@playwright/experimental-ct-react";
import { TextField } from "@mui/material";

test("this test causes vite/rollup failure", async ({ mount }) => {
await mount();
});

Expected behavior

Test builds and executes

Actual behavior

Error: [vite]: Rollup failed to resolve import "undefined" from "/Users/nathanpanchout/Documents/Societe/Clients/FunMooc/joanie/src/frontend/admin/playwright/index.tsx".
This is most likely unintended because it can break your application at runtime.
If you do want to externalize this module explicitly add it to
`build.rollupOptions.external`

Additional context

It's exactly the same problem as here: #29854.

However even with 1.43.1, the problem still seems to persist on my side, sorry

#29854 has just been fixed, and the fix will be released as a part of v1.44. You can try a canary release for now.
