v11.13: Vendor prefixes are present in CI but not in localhost

[marekdedic]

Hi,
while updated @emotion/react from 11.11.4 to 11.13.0, I encountered a strange issue - my test snapshots don't match and I can't update them.

See skaut/poptavky#1543 for an example of snapshot tests failing because of missing vendor prefixes

The problem is that when I run the tests locally, they all pass (i.e. vendor prefixes are not generated), but in GitHub Actions, they fail because emotion generated vendor prefixes.

I tried matching the Node version and that didn't help. I don't normally set NODE_ENV in either localhost or CI, but I tried doing that and it didn't help either... Any ideas? Thanks!
