templating overwrites "this" in <td> tag

I thought this was a handlebars error but this fiddle works fine: https://jsfiddle.net/onzew2s1/1/

Fiddle code:
```

Handlebars.registerHelper('stringify', function(arg1) {
return JSON.stringify(arg1);
});

global this: {{stringify this}} <br/>
table start <br/>
<table id="tiles">
<tbody>
{{#each tiles}}
<tr>
{{#each this}}
outside of td: {{stringify this}} <br/>
<td>
td: {{stringify this}}
</td>
{{/each}}
</tr>
{{/each}}
</tbody>
</table>
table done

```

It has this output:
```
global this: {"tiles":[["a","b"],["c","d"]]}
table start
outside of td: "a"
outside of td: "b"
outside of td: "c"
outside of td: "d"
td: "a" td: "b"
td: "c" td: "d"
table done
```

In contrast, my htmx code with the same input (shown to be identical with `stringify`):
```

Handlebars.registerHelper('stringify', function(arg1) {
return JSON.stringify(arg1);
});

```

has this output:
```
global this: {"tiles":[["a","b"],["c","d"]]}
table start
outside of td: "a"
outside of td: "b"
outside of td: "c"
outside of td: "d"
td: {"tiles":[["a","b"],["c","d"]]}
table done
```
