React errors when running unit tests of mobxjs/mobx repo

[kubk]

If I run yarn test -i inside mobx repo I get React errors like "When testing, code that causes React state updates should be wrapped into act(...)"

Here is an example: https://app.circleci.com/pipelines/github/mobxjs/mobx/1934/workflows/af361937-af86-41c2-9aff-87b52dd125d8/jobs/8678?invite=true#step-102-594

Is it OK to have react errors in unit tests? The error is gone if I follow the instruction and wrap component rendering in act. Should I create PR to fix all these React errors?

Should I create PR to fix all these React errors?

That would be awesome. I always forget about it.

EDIT: supressing all these (expected) warnings would be probably nice as well, not sure what the best practice is
