dedent_closing_brackets not working for Annotations[]

My config:
```init
[tool.yapf]
based_on_style = "google"
dedent_closing_brackets = true
coalesce_brackets = true
```

Generated diff:

I want to work this feature similar to how it works with functions:
```diff
- function(long_param_a, long_param_b, long_param_c)
+ function(
+ long_param_a,
+ long_param_b,
+ long_param_c,
+ long_param_d
+ )
```
