With 0 delay, if the `SettingsToolboxGroup` has been contracted via
button, there's no chance to be able to expand it via button again.
This is temporary at best just to keep things working somewhat, not sure
if the expansion logic will still be required in editor redesign, so
deciding to roll with it for now.
Might as well inline, but I feel like it will require adding the same
comment across all usages, because just `State.Value = Hidden` in an
until step feels off, dunno.
