Automation Smart value iterations don't have access to the original issue variable

Issue Summary

When iterating over a collection in smart values it would be useful to be able to access e.g. the original issue variable within the iteration.

Steps to Reproduce

{{#issue."Affected Status Page Components"}} "{{value.split("#").get(1)}}": "{{issue."Status Page Component Status"}}"{{^last}}, {{/}}{{/}} 

Expected Results

Expect to be able to access the `issue` variable

Actual Results

Returns an empty string rather than the issue variable

Workaround

The expression can sometimes be re-formed as a mapping over the collection rather than an iteration:

{{issue."Affected Status Page Components".value.split("#").get(1).concat(":").concat(issue."Status Page Component Status")}}
