Comment (by adeltahri):

 Hi @SergeyBiryukov I think if the excerpt contains only spaces it must be
 skipped and not saved in the database.
 if the developer tested $post->post_excerpt if it's empty or not, it will
 return true even with spaces only so we need to use trim() on the test, I
 think it will be good if we validate the input like when we add a new
 comment https://d.pr/i/OrPjEi
