I am using the playlist feature of the WordPress classic editor to add video playlists to my posts. (Videos are uploaded to the WordPress library, not hosted externally.)
It seems to be impossible to add the same video twice.
Even when editing the playlist shortcode on my own, in the end any video will be included only once in the playlist when the page is rendered. E.g. from this code the video with id 931 is only displayed once:
Is there any way to change this behavior and allow adding the same video to a playlist multiple times?
