ReferenceError: regeneratorRuntime is not defined

[igoldny]

Describe the bug

After installing addon-visual-tests on our repo some stories got broken. We get ReferenceError: regeneratorRuntime is not defined error in stories and chromatic test run is failing on those stories.

Just to be clear those stories working prefectly fine without addon-visual-tests.

After diving into the error, it is happening on stories where we use internal old package that we cannot update since it deprecated but some team still using it and we'll have to support it for a while. This is a dropdown package using old downshift version (details below)

To reproduce

to mimic the internal package you can try to create package with the following dependencies:

"dependencies": {
"cypress-wait-until": "^1.7.1",
"downshift": "^6.1.7",
"lodash.debounce": "^4.0.8",
"lodash.differencewith": "^4.5.0",
"lodash.isequal": "^4.5.0",
"prop-types": "^15.7.2",
"react-virtualized": "^9.22.3",
"stickyard": "^0.3.0"
}

Environment

OS X - Chrome -Storybook 8 - "@chromatic-com/storybook": "^1.3.3" But happens in chromatic cloud as well You can dm me if you want me to provide chromatic build url.
