3-levels nested #each not working as expected!

[ramrami]

I'm facing this weird issue with nested each helpers using the same parent data, where there is one iteration skipped from the inner loop :

I've made a reproduction in the playground here.

Template:

<ul class="people_list">
  {{#each people}}
    <li>Loop 1 - {{@index}} - {{this}}</li>
    {{#each ../people}}
    	<li>Loop 2 - {{@index}} - {{this}}</li>
        {{#each ../../people}}
        	<li>Loop 3 - {{@index}} - {{this}}</li>
        {{else}}
        	<li>Loop 3 - No data!!</li>
        {{/each}}
        
    {{/each}}
    
  {{/each}}
</ul>

Using the input:

{
  people: [
    "Yehuda Katz",
    "Alan Johnson",
    "Charles Jolley",
  ],
}

The output (notice when loop1 index is the same as loop2 index then loop3 is skipped):

<ul class="people_list">
    <li>Loop 1 - 0 - Yehuda Katz</li>
    	<li>Loop 2 - 0 - Yehuda Katz</li>
        	<li>Loop 3 - No data!!</li>
        
    	<li>Loop 2 - 1 - Alan Johnson</li>
        	<li>Loop 3 - 0 - Yehuda Katz</li>
        	<li>Loop 3 - 1 - Alan Johnson</li>
        	<li>Loop 3 - 2 - Charles Jolley</li>
        
    	<li>Loop 2 - 2 - Charles Jolley</li>
        	<li>Loop 3 - 0 - Yehuda Katz</li>
        	<li>Loop 3 - 1 - Alan Johnson</li>
        	<li>Loop 3 - 2 - Charles Jolley</li>
        
    
    <li>Loop 1 - 1 - Alan Johnson</li>
    	<li>Loop 2 - 0 - Yehuda Katz</li>
        	<li>Loop 3 - 0 - Yehuda Katz</li>
        	<li>Loop 3 - 1 - Alan Johnson</li>
        	<li>Loop 3 - 2 - Charles Jolley</li>
        
    	<li>Loop 2 - 1 - Alan Johnson</li>
        	<li>Loop 3 - No data!!</li>
        
    	<li>Loop 2 - 2 - Charles Jolley</li>
        	<li>Loop 3 - 0 - Yehuda Katz</li>
        	<li>Loop 3 - 1 - Alan Johnson</li>
        	<li>Loop 3 - 2 - Charles Jolley</li>
        
    
    <li>Loop 1 - 2 - Charles Jolley</li>
    	<li>Loop 2 - 0 - Yehuda Katz</li>
        	<li>Loop 3 - 0 - Yehuda Katz</li>
        	<li>Loop 3 - 1 - Alan Johnson</li>
        	<li>Loop 3 - 2 - Charles Jolley</li>
        
    	<li>Loop 2 - 1 - Alan Johnson</li>
        	<li>Loop 3 - 0 - Yehuda Katz</li>
        	<li>Loop 3 - 1 - Alan Johnson</li>
        	<li>Loop 3 - 2 - Charles Jolley</li>
        
    	<li>Loop 2 - 2 - Charles Jolley</li>
        	<li>Loop 3 - No data!!</li>
        
    
</ul>

Is this a bug or am I doing something wrong?
Please help.

Yes, this is a bug: #1686

As a workaround you can use @root:

<ul class="people_list">
  {{#each @root.people}}
    <li>Loop 1 - {{@index}} - {{this}}</li>
    {{#each @root.people}}
    	<li>Loop 2 - {{@index}} - {{this}}</li>
        {{#each @root.people}}
        	<li>Loop 3 - {{@index}} - {{this}}</li>
        {{else}}
        	<li>Loop 3 - No data!!</li>
        {{/each}}
    {{/each}}
  {{/each}}
</ul>
