In browser mode, it seems that the iframe is destroyed every time after executing the test.

Can we keep the iframe so that I can inspect the component's UI?

I am using @testing-library/react. I did not manually call cleanup, but the DOM is indeed being destroyed. According to the official documentation, it seems to automatically clean up, and I couldn't find a manual way to close it.

You need to set PTL_SKIP_AUTO_CLEANUP to true: https://testing-library.com/docs/preact-testing-library/api/#cleanup

PTL_SKIP_AUTO_CLEANUP=true vitest --browser

Setting this environment variable didn't work. I found that as long as I enable globals configuration, the DOM would be destroyed after the test execution, and the DOM would be retained only if I disabled the globals configuration.

I am now heavily reliant on enabling the globals configuration because I am using vitest in a rush monorepo. To avoid installing vitest dependencies in every package, I have created a separate package, such as my-vitest. Therefore, I import test files from this package, and if I want to use the vi.mock method, I must enable the globals configuration.

Sorry, I linked you the preact name, you need to use RTL_SKIP_AUTO_CLEANUP instead
