I'm trying to implement a form class that allows me to better implement working with forms in Svelte, but I'm running into the issue that when I update a instance property inside the 'use' action function... the new value is not getting updated in the view.

Here is the link to a REPL I'm working with:

https://svelte.dev/repl/13ac33881a184795947be6ae9f104834?version=3.44.3

Essentially what I'm trying to achieve in this piece of code is that when the user clicks into the input, the inputs bounded class instance 'touched' property gets updated in the 'use' action, which should in turn, re-render the 'touched' value in the UI.

I'm not sure why the value is not updating in the UI.

Any help to make understand what I'm doing wrong is greatly appreciated.
