Login Popup takes much to long until it disappears

Hello,
I noticed that the login popup takes extremely long until it disappears. Same for cart popup. At cart popup, I could solve this via css but for login popup, I had to edit etheme.js.
In line 1941 I found:

    var loginTimeout = 0;

    $( ".login-link" ).hover(
      function() {
        clearTimeout(loginTimeout);
        $( '.login-popup' ).addClass( 'hover_login' );
      },
      function() {

        loginTimeout = setTimeout(function () {
            $( '.login-popup' ).removeClass( 'hover_login' );
        }, 1500);
        
      }
    );

Whats the sense of this long timeout? Why isnt this done via css? I deleted the timeout completely and I wanted to ask if you could also remove this for the next update because it makes no sense and can be done via css….?
