   * A single static vnode can contain stringified content for **multiple**
   * consecutive nodes (element and plain text), called a "chunk".
   * `@vue/runtime-dom` will create the content via innerHTML in a hidden
   * container element and insert all the nodes in place. The call must also
   * provide the number of nodes contained in the chunk so that during hydration
   * we can know how many nodes the static vnode should adopt.
   *
   * The optimization scans a children list that contains hoisted nodes, and
   * tries to find the largest chunk of consecutive hoisted nodes before running
   * into a non-hoisted node or the end of the list. A chunk is then converted
   * into a single static vnode and replaces the hoisted expression of the first
   * node in the chunk. Other nodes in the chunk are considered "merged" and
   * therefore removed from both the hoist list and the children array.
   *
   * This optimization is only performed in Node.js.
