coalesce_brackets not working together with dedent_closing_brackets

Yapf 0.16.3. Test file (what I want/expect):
```
with something:
for more in indentation:
base_html = base_template.render({
'header': self.header,
'pages': included_pages,
'footer': self.footer
}) # <--- I want the closing } and ) together on a separate line

```

With both true:
```
[style]
based_on_style = pep8
column_limit = 99
coalesce_brackets = true
dedent_closing_brackets = true
```
gives:
```
