lightning-formatted-date-time - showing previous date (LWC)

I am using the tag "lightning-formatted-date-time" in my lightning web components with the value "2019-06-02" but it is displaying the previous date.

I am not getting if the value is not a valid one for the tag. Please suggest.

Here is the playground code.
