Answer 2

The mode of the ShadowRoot: either "open" or "closed". Setting the
mode of a shadow root to "closed" makes the shadow root’s
implementation internals inaccessible and unchangeable from
JavaScript—in the same way the implementation internals of, for
example, the <video> element are inaccessible and unchangeable from
JavaScript.
