I remembered why I used [...field.path.toArr(), name] instead of `${field.path}.${name}` while writing this document, #1727 (comment)

It was because events listening to pattern ${field.path}.${name} will fail to dispatch if the component is used as an item of an array field, so I usually avoid writing in this "recommended way". Here is a reproduce, https://codesandbox.io/s/objective-wilbur-n2fqe
