Inconsistent format - option weekday: 'long' between  Intl.DateTimeFormat and toLocaleDateString

if I use  **toLocaleDateString** on polyfilled method with weekday option I get an incorrect date format
new Date().toLocaleDateString([], {
            timeZone: undefined,
            weekday: 'long'
          })
**"‎Thursday‎, ‎1‎ ‎23‎, ‎2020"**

new Intl.DateTimeFormat([], {
            timeZone: undefined,
            weekday: 'long'
          }).format(new Date())
**"‎Thursday"**
