When the element is pre-selected and the Tree component is mounted,
right now we are only applying initial vertical offset, but not the
horizontal one.

Because of this, if the DOM element was selected on Elements panel and
then user opens Components panel for the first time of the browser
DevTools session, depending on the element's depth, it could be hidden.

Similarly to vertical offset, apply horizontal one, but via ref setter.
