[@web/test-runner-visual-regression] Node is detached from document

[petergaal91]

I get an Node is detached from document issue since @web/test-runner version 17, if I use the @web/test-runner-visual-regression package in my tests. I created a repo to reproduce my issue: https://github.com/petergaal91/wtr-snapshot

I defined 2 web components and 2 test files. If I run the card.component.spec file only, it's works perfectly, but if I run more than 2 test files I see this error message:

npm run test

> [email protected] test
> npx wtr --config ./wtr.config.mjs

Chrome: |██████████████████████████████| 2/2 test files | 7 passed, 1 failed

Finished running tests in 2.6s with 1 failed tests.

If I downgrade these packages, it's works perfectly:

"@web/test-runner": "0.16.1"
"@web/test-runner-chrome": "0.13.0"

I see puppeteer upgraded in version 17, so I'm not 100% sure it's wtr related or not. I didn't found any puppeteer related issue for this error.

I'm seeing this as well with the @web/test-runner-visual-regression.
