I have the same issue in macOS Big Sur 11.4. I have to add the command `defaults` by myself.

Try mock .css file by `jest-transform-stub`: ```js module.exports = { ... moduleNameMapper: { '^.+\\.(css|styl|less|sass|scss|png|jpg|ttf|woff|woff2)$': 'jest-transform-stub', ... } } ```

It may cause memory leak issue if the event is bound every time at the start of connection and never be unbound at the stop of connection.

> Does the commented-out `$(window).unbind('unload');` work-around the issue? I know it's still a bad issue. Just curious. Yes!! Unbind unload event self would be solve this issue.
