How do I prevent React Router 4 from re-rendering on URL switch?

I am having a hard time trying to preventing React Router 4.1.2 (latest) from restting my forms when I am switching the tabs in my application.

Here's my structure:

Root component:

<Route path="/" component={Content}/>

Content component:

import React, {Component} from 'react'
import {connect} from 'react-redux'
import {Redirect, Route, Switch} from 'react-router-dom'
import {history} from 'configureStore'
import * as actions from 'actions/tabs';
import {Divider, Input} from 'semantic-ui-react'
import Tabs from 'components/Tabs'
import Dashboard from 'components/Dashboard'
import ProfileList from 'components/ProfileList'

class Content extends Component {
  render() {
    const {tabs, switchTab, closeTab} = this.props
    let componentByName = {
      Dashboard: Dashboard,
      ProfileForm: ProfileForm,
      ProfileList: ProfileList
    }
    let routes = []

    tabs.forEach((tab) => {
        routes.push(<Route key={tab.id} exact path={tab.path} component={componentByName[tab.component]}/>)
    })

    return (
      <div>
        <Tabs list={tabs} onClick={switchTab} onCloseClick={closeTab}/>

        <Divider hidden/>

        <Switch>
          {routes}
        </Switch>
      </div>
    )
  }
}

const mapStateToProps = (state) => ({
  tabs: state.tabs
})

export default connect(mapStateToProps, actions)(Content)

How can I just hide/show the content without losing anything from the tabs I switch from?
