This will still remove the `WI.View` from the parent `_subviews` even though the node wont be removed from the DOM, right?

Can we somehow confirm that removing an extension does in fact GC all the related objects?

I would _strongly_ prefer that this be on `WI.WebInspectorExtensionTabContentView` instead of the more generic `WI.TabContentView` as the latter shouldn't ever need this mechanism (i.e. it should _always_ use `WI.View.prototype.removeSubview`)
