Unexplained Facebook URL_Embed features lost during upgrade from Open Social 10.3.x to 11.0.10

I don't know if this will be of much help, but I pulled the rendered code via my "inspector" to see the difference between the post in Sample 1 above to see the difference between versions

Before update - Inspect element from social 10.3.8

More Information! As I seek to troubleshoot what changes in Open Social or Social Embed and their related dependencies have been modified that are causing these feature degradations.

This issue is about losing the ability to have Oembed work in posts with Facebook URL's and was created by updating Open Social from version 10.3.8 to ^11.0.10 primarily.

After doing an update within Open Social 10.3.8 a Facebook Embeded IFrame with dimensions of 500 by 506 which prior to the update shrunk from it's full dimensions to about 70 pixels high after the update.

As I scroll through our Home Stream, I see that any instance of a Facebook embed IFrame that once rendered as coded is now cropped dramatically beyond recognition. I also see that embed videos from other sites like Ted (Talks) which displayed properly, are now cropped as well!

<iframe src="https://www.facebook.com/plugins/post.php?href=https%3A%2F%2Fwww.facebook.com%2FAreYOUontheCrewList%2Fposts%2F160607126347701&show_text=true&width=500" width="500" height="506" style="border:none;overflow:hidden" scrolling="no" frameborder="0" allowfullscreen="true" allow="autoplay; clipboard-write; encrypted-media; picture-in-picture; web-share"></iframe>

Also: This truncation ONLY happens on the Stream Pages. If you edit the post and display it in the post's own URL ie: /post/509, The post appears as it should!

Here is what was updated and the only item(s) that needed a database update following composer uppdate --with-dependencies) related to Blazy (Who I suspect may be the culprit)

This has been resolved in social 11.3.6 in combination with working through appropriate OEmbed permissions with Meta/Facebook

Changing status to closed - fixed!
