It looks like after recent updates of CSS the body of popup in the Chrome extensions tray is broken. Although it has flex set and max-width, it seems nothing is pushing the content up to its desired boundaries.
Thanks for the report, I finally go the 116 version update for Chrome myself and I've posted new version 2.8 of the addon with a fix. Should be up in few days.
