Question

Answer 1

Last time I've used

map._onResize(); 

and that help me refresh map. Maybe a little hack, but, it work.

In your code will be area._onResize()

P.S: Maybe you should try change the way to set new opacity value - try change

function clicked(){
    this.options.style.fillOpacity = 0.8;
 }

to that

function clicked(){
    this.setStyle({fillOpacity: 0.2});
 }
