In a nutshell Safari does not support ResizeObserver fully yet, so AvatarRow and any other things that use it don't work as expected.
Solution
In this PR we add the polyfill @juggle/resize-observer to be used only on Safari. We can remove it when Safari supports RO properly (allegedly v15.4 which is coming soon).
