/**
* React-compatible event handling for form interactions.

* React uses synthetic events and doesn't detect direct DOM manipulation.
* This module provides JavaScript snippets that can be injected via Runtime.evaluate
* to properly trigger React's event system.

/**
* JavaScript function to fill an input element in a React-compatible way.
*
* This approach:
* 1. Uses native property setters to bypass React's value tracking
* 2. Dispatches input/change events that React listens for
* 3. Properly handles focus/blur for form validation
*
* @remarks
* Works with React, Vue, Angular, and vanilla JS applications.
