  Messages sent to Playwright are packaged up internally in `ChannelMessage`
  data structures.

  Before being dispatched to Playwright, a monotonically
  incremented `id` is added. This `id` is used to match related messages
  received from the server. Those received messages ofter represent a form
  of "completeness".
