Cannot display 0 in FormattedMessage

[iamsaksham]

I want to display size of the list in the FormattedMessage, so I used values to achieve it. It works good but it dont show 0 as a value. I have a reduced test case below:

import React, { Component } from 'react'
import {FormattedMessage} from 'react-intl'

class List extends Component {

  render() {

    let userNumber=0; //if I change it to negative or positive value, it is displayed but 0 is not displayed
    return (
          <FormattedMessage
            id = 'active-users'
            description = 'ACTIVE USERS'
            defaultMessage = 'ACTIVE USERS ({userList})'
            values = {{
              userList: userNumber
            }}
          />
     )
  }
}
export default List

<FormattedMessage
    id = 'active-users'
    description = 'ACTIVE USERS'
    defaultMessage = 'ACTIVE USERS ({userList, number})'
    values = {{
      userList: userNumber
 }}/>

This needs to be done, documentation needs to be improved a bit.
