I think it is possible to recreate with Click interactions, applied to the form fields.
In short, it would be like this:
you click on field (which is focusing) ----> appropriated div get opacity 100%.
you click on other field --------> previous div get 0% opacity, appropriated div get 100% opacity
you click to some other element (form, container, section, etc) -------> all divs get opacity 0%
