Preview-link of YouTube-video should include playlist-parameter

Use-case: wanting to share a YT-video inside a playlist. 
Copying the URL, there's a list-parameter, to identify the playlist. 

The generated preview in the Discord-text-chat has a link, this link ignores/removes the list-parameter, but does keep other parameters like e.g. the t-/start-parameter for start-time. 

When clicking the thumbnail instead of the original link in text-form, the correct video opens, but without a playlist.
