    Don't unnecessarily tear down top layer renderers in RenderTreeUpdater

    Reviewed by Antti Koivisto.

    The element.isInTopLayer() check added by 
https://commits.webkit.org/246767@main is there is because
    entering top layer forces `display: contents` style to `display: block`. 
This check is now redundant
    with https://commits.webkit.org/255527@main, since it is fixing the same 
issue more globally.
