Email template rendering issue by using Theme


I am using Cakephp Theme concept for my project, currently not able to use the email template from the source to theme.

It is working fine when I overload Templates, Elements etc. But when it comes to Email template, I am not able to overload and an error message : Email Template not found is appearing as a response. So is this issue of Framework.

For testing I tried to append the theme name as a model to the Email::setTemplate(ThemeName.emailTemplate), which worked. Which means, placement of file is fine in the Theme, the issue is something different.

Could you please verify this and let me know.
