Admin: Bind tab to the URL

[sophiamersmann]

In #3793, while refactoring the chart editor, I have removed the tab binder since it wasn't working. We might want to add it back in the future.

@observer
class TabBinder extends React.Component<{ editor: ChartEditor }> {
    dispose!: IReactionDisposer
    componentDidMount(): void {
        //window.addEventListener("hashchange", this.onHashChange)
        this.onHashChange()

        this.dispose = autorun(() => {
            //setTimeout(() => window.location.hash = `#${tab}-tab`, 100)
        })
    }

    componentWillUnmount(): void {
        //window.removeEventListener("hashchange", this.onHashChange)
        this.dispose()
    }

    render(): null {
        return null
    }

    @action.bound onHashChange(): void {
        const match = window.location.hash.match(/#(.+?)-tab/)
        if (match) {
            const tab = match[1]
            if (
                this.props.editor.grapher &&
                this.props.editor.availableTabs.includes(tab)
            )
                this.props.editor.tab = tab
        }
    }
}
