Using another set of steps: 1. Launch browser. 2. Load any of the links: https://www.twitch.com 3. Put the autoplay video in full screen. Expected result: The video is properly played on full screen. Actual result: A black screen is displayed; the user cannot exit this state, only system restart. (CMD+OPT+ESC hotkey also not usable). This issue was reproduced on a build that does not have the new sandbox feature (18-10-2021). This being said, we can safely assume that this issue is not related to the sandbox implementation.
