Video from streamable.com… Maybe a total edge case, but fyi.
I was sort of surprised when I pasted the link into the message box when I posted it that the video actually displayed correctly, at least on the desktop version, even though it replays when it reaches the end. But on the mobile version of the site, the video is cut in half, and the video controls are inaccessible.
When I tried posting a link to the video here and previewed the post, the video displayed in full but overlapped the text below it.
