🐛 Bug Report

When using React concurrent mode (a 16.X release initially planned for Q2 2019 and not yet stable, but used in prod at facebook), the following error occurs when trying to call useTranslation within a lazy-loaded component with suspense.

To Reproduce

React concurrent mode with console warning: https://codesandbox.io/s/react-i18next-lazy-loading-example-forked-ozkgn

Expected behavior

No console warning and no side effect.
Expecting the same behavior as @jamuhl's example with React 16.12: https://codesandbox.io/s/react-i18next-lazy-loading-example-forked-kv2cr

update react-i18next to 11.7.2 should already solve this?

@jamuhl oh boy... Was running on 11.7.0 and incorrectly assumed that I was on the latest version (having renovate auto-create PRs for package upgrades). bumping to 11.7.2 indeed resolved the issue.
Sorry for all the messages, and thanks for the quick replies!
