Hey folks- We're running into an issue where if we have videos in a carousel (we use Brightcove and Youtube for video hosting), if the user clicks the full-screen icon while in Safari, the browser attempts to full-screen the whole page, and not the video. This only happens when the video is in a carousel. Here are 2 code pens illustrating the issue. Notice the difference between how the videos render at full-screen while in a carousel compared with the standalone videos.

This works fine in Chrome & Firefox

Confirmed not working properly in:
Safari Version 15.4 (15613.1.17.1.13, 15613) on MacOS 10.15.7 (19H1824)
Safari Version 15.5 (16613.2.7.1.9, 16613) on MacOS 11.6.6 (20G624)
