`container: document.body` breaks tests

<!-- Thanks for your interest in the project. We appreciate bugs filed and PRs submitted! --> <!-- - For questions related to using the library, please join the Discord server (https://discord.gg/testing-library) instead of filing an issue on GitHub. - Please fill out this template with all the relevant information so we can understand what's going on and fix the issue. - If you're issue is regarding one of the query APIs (`getByText`, `getByLabelText`, etc), then please file it on the `@testing-library/dom` repository instead. Thanks :) ---> **Describe the bug** A clear and concise description of what the bug is. When having a teleport to body in a component you want to set `attachTo` of vue test utils to `body`, to do so you can set `container: document.body` in testing library. This causes a problem that now `render` will remove the `body` node and causes `document.body` to be `null` after calling `render`. **To Reproduce** Steps to reproduce the behavior: <!-- Please try to provide a working demo using Codesandbox, a GitHub repo or similar! --> Have a component that teleports to body and then set the container to the body. **Expected behavior** No issues. <!-- A clear and concise description of what you expected to happen. --> **Related information:** - `@testing-library/vue` version: 8.1.0 - `Vue` version: 3.5.25 - `node` version: 24 - `npm` (or `yarn`) version: 11 **Additional context** <!-- Add any other context about the problem here. --> This is caused by this line in the `render.js`: ```js unwrapNode(wrapper.parentElement); ``` This fixes it: ```js if (baseElement !== container) { unwrapNode(wrapper.parentElement); } ```
