Emitted when the `WebContents` gains focus. Emitted when the `WebContents` gains focus.
Note that on macOS, having focus means the `WebContents` is the first responder
of window, so switching focus between windows would not trigger the `focus` and
`blur` events of `WebContents`, as the first responder of each window is not
changed.
The `focus` and `blur` events of `WebContents` should only be used to detect
focus change between different `WebContents` and `BrowserView` in the same
window.
