This change was made using LocalStorage implemented inside of the component. I'm not sure it's the best solution because of most of the other LocalStorage values are implemented using stores. In this way, I want feedback about my approach and I'm willing to keep working on this issue until it is resolved.

I've added the cypress test and would be delighted if you could review it - It is the first time I work with cypress :). Also, I've removed the try/catch block. It does not seems to be necessary.
