In the Safari desktop browser only, all videos that we add from Cloudflare Stream > Embed Code have a black margin on either the side or bottom.
This happens only in Safari Desktop, not Google Chrome.
If you drag-and-resize the window eventually the black margin goes away.
The aspect ratio of the video, which Cloudflare Stream uses to calculate the padding-bottom, looks correct. We don’t have any extra margin built into our videos. The source of the problem seems to be in Cloudflare’s iframe itself
