We do not fire `beforeinput` events since other browsers do not seem to do so either. The spec asks us to check whether a command's action modified the DOM tree. This means adding or removing nodes and attributes, or changing character data anywhere in the tree. We have `Document::dom_tree_version()` for node updates, but for character data a new version number is introduced that allows us to easily keep track of any text changes in the entire tree.
