`where_density = "Vertical"` behaves like `where_density = "Tall"`

[regexident]

There doesn't seem to be a difference between:

where_density = "Tall"

and:

where_density = "Vertical"

Looking at the code the latter doesn't even appear to be taken into account for where_density at all (only for fn_args_density).
