Hi, I have a problem using master/detail view.
When I navigate back, goes an error or the master page disappear.
am I doing something wrong or is it a bug?
Thanks!

my code:

import { App, Button, f7, Navbar, NavTitle, Page, PageContent, View } from "framework7-react";
import { Framework7Parameters } from "framework7/types";
import React from "react";

export default class AppMaster extends React.PureComponent {

    render() : JSX.Element {

        const params = {
            theme: 'auto', 
            name: 'Test', 
            id: 'net.test',
            routes: [
                {viewName: 'main', path: '/', master: true, component: ScreenHome, 
                    detailRoutes: [
                        { path: '/:Id', component: ScreenItem },
                    ]
                },
            ]
        } as Framework7Parameters;

        return(
            <App {...params} >
                <View main
                    browserHistory={true}
                    masterDetailBreakpoint={800}
                    masterDetailResizable={true}
                    browserHistoryStoreHistory={false}
                >

                </View>
            </App>
        );
    }
}

class ScreenHome extends React.PureComponent {

    render() : JSX.Element {
        return (
        <Page>
            <Navbar>
                <NavTitle>Home</NavTitle>
            </Navbar>
            <PageContent>
                <Button text="Button 1" onClick={() => f7.view.main.router.navigate('/1')} />
                <Button text="Button 2" onClick={() => f7.view.main.router.navigate('/2')} />
            </PageContent>
        </Page>
        );
    }
}

class ScreenItem extends React.PureComponent {
    render() : JSX.Element {
        return (
        <Page>
            <Navbar>
                <NavTitle>Item</NavTitle>
            </Navbar>
            <PageContent>
                Item 
            </PageContent>
        </Page>
        );
    }
}
