Regression: capture groups should be able to match empty string

[evashort]

SSCCE:

module Main exposing (main)

import Browser
import Html exposing (Html, text)
import Regex

view : Html Never
view =
    text -- first submatch should be Just "" instead of Nothing
        ( Debug.toString
            ( Regex.find
                ( Maybe.withDefault
                    Regex.never
                    (Regex.fromString "(.*)")
                )
                ""
            )
        )

main : Program () () Never
main =
    Browser.sandbox
        { init = ()
        , view = always view
        , update = always identity
        }

The correction is as follows.
But I can't check it because I don't know how to run the test program with Elm native code in my local project on Elm 0.19.
