Javascript filter on for issues is not executed correctly

Xporter does not validate javascript filter correctly on Excel templates.
If you have a for issues like:

&{for issues|filter=%{'${IssueTypeName}'.equals('Story') || '${IssueTypeName}'.equals('Test')}}

The export only shows issues of type Story. However, if this code is executed on Word templates, the result is both Story and Test issue types.

An example is attached to this issue.
