When installing the package @devexpress/dx-react-grid-bootstrap4, it's throwing a warning about the peer dependencies caused by its depency package react-popper.
@devexpress/dx-react-grid-bootstrap4 version: 4.0.5 react-popper version: 2.2.5
This issue is resolved in the version 2.3.0 of react-popper.
I tried to submit a pull request in the devextreme-reactive repository but I wasn't able to (the PRs are limited to contributors).
I'm opening this issue in the hope that a contributor of that devextreme-reactive sees this and opens it themselves.
