Fix: Simplify the widget state logic (#6741)

## Summary

Fixes the case where a value is updated in the graph but the result
doesn't reflect on the widget representation on the relevant node.

## Changes

- **What**: Uses vanilla Vue utilities instead of a special utility
- **What**: Fewer places where state could be desynced.
