Latest version `7.1.0` appears to break tests using `enzyme`

Bug Description

When running tests using enzyme in CRA app, the following error occurred:

Test suite failed to run

    ReferenceError: TextEncoder is not defined

    > 1 | import { configure } from 'enzyme';
        | ^

Expected Behavior

The same tests didn't break when I ran them in my environment last week, and undici v7.1.0 appears to just be just released couple of days ago.

Logs & Screenshots

Environment

node 20.11.0
enzyme 3.11.0

Additional context

Start with the undici/lib/web/fetch/data-url.js stack entry and the reproduction linked in the issue, then inspect how undici v7.1.0 is loaded from src/setupTests.js in the CRA example. Confirm the failure on Node 20.11.0 with enzyme 3.11.0, and consider the issue done when the test suite runs without the TextEncoder error while preserving supported runtime behavior.
