Web Inspector: collapsing a virtualized folder in a `WI.TreeOutline` doesn't updated the DOM
https://bugs.webkit.org/show_bug.cgi?id=206302

Reviewed by Timothy Hatcher.

* UserInterface/Views/TreeOutline.js:
(WI.TreeOutline.prototype._updateVirtualizedElements):
When collapsing a currently visible `WI.TreeElement`, it will still be in the cached set of
visible and attached `WI.TreeElement`s, meaning that `_updateVirtualizedElements` will early
return since it thinks that the same `WI.TreeElement` are being shown. Add another check to
ensure that it only thinks that if the same number of `WI.TreeElement` are visible.
