The keybindings are duped for the new code folding (previously set to next/prev view). I edited my User key bindings to this, which fixes it:
{ "keys": "super+alt+"], "command": "fold" },
{ "keys": "super+alt+]"], "command": "unfold" },
{ "keys": "super+shift+"], "command": "prev_view" },
{ "keys": "super+shift+]"], "command": "next_view" }
