This trait represents the root of your Scala DOM Builder tree. It represents the root of the DOM subtree that you manage with Scala DOM Builder, not the whole DOM Document.
Scala DOM Builder assumes that you do not manipulate DOM nodes represented by this subtree outside of Scala DOM Builder (e.g. by using other libraries or calling native JS DOM functions directly) in ways that would have affected the state of your Scala DOM Builder tree if those changes were made using Scala DOM Builder.
So for example, moving a real DOM node that is represented in your Scala DOM Builder to a different parent would cause the real DOM hierarchy to become inconsistent with the parent-children links that are recorded in your Scala DOM Builder tree. If you then do anything that relies on those links to be correct, your code would produce unexpected results.
On the other hand, if you say update an attribute of some real DOM node without going through Scala DOM Builder, that is completely fine because Scala DOM Builder by itself does not keep track of the attributes that exist on DOM nodes. Your application code might, but after
attr := valuesetter is executed, it is normally discarded.Note: Scala DOM Builder doesn't actively police its DOM tree for inconsistencies with the real DOM.
