Comment (by madhatter2099):

 If I explicitly set an excerpt then it will display properly. It only
 seems to be when there's no excerpt that it doesn't get the correct
 excerpt. Using the apply_filters() function most likely isn't working
 since
 {{{ get_post_field('post_excerpt', $post) }}}
 returns an empty string, which get_the_excerpt() won't know what to do
 with. I found the solution on another site so I'm not confident it's a
 proper solution anyway, I'd rather focus on getting the get_the_excerpt()
 function working.

 I also see no reason that the WP_Post Class couldn't have an excerpt
 method added to it which either returns the excerpt or generates one.
