### Variables

`read onlylength:Int`

Returns an `Integer` representing the number of elements in the session history, including the currently loaded page. For example, for a page loaded in a new tab this property returns `1`.

###

`scrollRestoration:ScrollRestoration`

Allows web applications to explicitly set default scroll restoration behavior on history navigation. This property can be either `auto` or `manual`.
