Google Chrome will require cross-origin isolation when using SharedArrayBuffers from Google Chrome 91 onward (2021-05-25) for Web Compatibility reasons. Additional details can be found on: https://developer.chrome.com/blog/enabling-shared-array-buffer/. When set to Enabled, sites can use SharedArrayBuffer with no restrictions. When set to Disabled or not set, sites can only use SharedArrayBuffers when cross-origin isolated.
