Meta description for stream item

Hello,

In analyzing my SEO, I realized an inconsistency for the streams items pages.

Depending on the post type, the value of <meta name = "description" varies a lot.
I invite you to watch the screenshots, it's clearer.

This meta description can be :
the description of the link,
the text status of the photo publication,
the text status of the video publication.

And for the simple status publication, there is simply no description. Ditto for video posting where there is no text status.

This should probably be harmonized, and especially add a meta description to all types of publications.
By retaking the text status if there is one, or else the description of the video.
This is to optimize the SEO

Thank you,
Philippe
