get_template_part Support

Hello.
I’m not sure where to post it, sorry if i’m missed. But i have some question. Is plugin support get_template_part() as repeater template content?

If i paste raw content to content area of template it owrks perfectly, but when i put there something like that:
<?php get_template_part('parts/content','message-list'); // Message list item ?>
Plugin loads nothing. Is it ok behavior, or i missed something?
