[10.0.0-rc.0] Issue with forwardRef in material ui SwipeableDrawer

See original GitHub issue

When creating a very basic app with just a render fn of:

                <SwipeableDrawer open={show_sidebar} onOpen={() => this.setState({ show_sidebar: true })} onClose={() => this.setState({ show_sidebar: false })}>
                    <Sidebar />
                </SwipeableDrawer>

based on latest material-ui I get the following issues with preact. If I switch to react it works fine with no errors

debug.module.js:2 Failed ForwardRef(Modal) type: Invalid ForwardRef(Modal) `children` supplied to `<ForwardRef(Modal) BackdropProps="[object Object]" BackdropComponent="function WithStyles(ForwardRef(Backdrop))() {}" className="MuiDrawer-root MuiDrawer-modal" open="true" onClose="function onClose() {}" ref="undefined" class="MuiDrawer-root MuiDrawer-modal" />`. Expected an element that can hold a ref. Did you accidentally use a plain function component for an element instead? For more information see https://material-ui.com/r/caveat-with-refs-guide

@marvinhagemeister I will try to make a minimal reproducible example repository before I make a new issue. It’s kind of a complicated setup with Gatsby, Preact and Material UI and I’m not 100% sure who’s to blame.
