When using the oEmbed Lazy load module with Drupal, there is a susceptibility in Drupal's behavior where the intersection-observer script attached to Drupal removes the data-src attribute and copies its value to the src attribute of iFrame. This process works fine the first time but fails the second time as the data-src attribute has already been removed, causing the script to throw an error.
To fix the issue, we have added a wrapping if condition in the intersection-observer script. This condition checks if the data-src attribute exists before swapping it with the src attribute. If the attribute does not exist, the script skips the swapping process and moves on to the next video.
Test the updated module thoroughly to ensure that the fix is working as intended.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Thanks for reporting this. I did some testing and it looks like this happens only if big pipe is enabled.
I will do some more testing tonight and if all looks good, will cut a release with this resolved Sunday.
