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

[brookabyss]

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"
