`title` argument passed to nested `@OptionGroup` has no effect
@OptionGroup
behaves in an unexpected way with nested groups when title:
argument value is specified.

Steps to Reproduce
Create a type that has properties using @OptionGroup
property wrapper with title:
argument passed. Uses this type then as @OptionGroup
itself. This top level may specify or not specify its own title:
argument, this doesn't make a difference on the observed outcome.
Expected behavior
Nested @OptionGroup
s have their title:
values displayed and options grouped by these titles in help output.
Actual behavior
Nested @OptionGroup
s don't have their title:
values displayed and options grouped by these titles in help output. All of the options are displayed within the top-level group, title:
values on nested groups have no effect whatsoever.
