// The preferable way to focus the component. When requestFocus() is called,
// the actual focus() will be deferred, and if requestFocus() has been
// called for several components, only one of those components will actually
// get a focus() call. By default, last component for which requestFocus() is
// called will get a focus() call, but you can specify arbitrateFocus property
// of a parent View and provide the callback to decide which one of that View's
// descendants should be focused. This is useful for the accessibility: when
// consecutive focus() calls happen one after another, the next one interrupts
// the screen reader announcement for the previous one and the user gets
// confused. autoFocus property of focusable components also uses requestFocus().
