willDestroyElement not firing in {{each}} else

[amk221]

A.                            |     B.
{{#each items as |item|}}     |     {{#each items as |item|}}
  {{!...}}                    |        {{!...}}
{{else}}                      |     {{/each}}
  {{my-component}}            |     {{#unless items.length}}
{{/each}}                     |       {{my-component}}
                              |     {{/unless}}

In example A. the willDestroyElement hook is not firing for {{my-component}} when it is torn down.
It works for example B.
