Nested brackets split across multiple lines formats incorrectly with `continuation_align_style = fixed`

An example best illustrates the issue. Clearly, the sample code (pre-formatting) should be left unchanged by yapf, but its indentation is instead messed up.

Sample code (pre-formatting)
```python
foo = Foo(
[
(0, 1),
(0, 1),
(0, 1),
(0, 1),
],
[],
)
```

Sample code (post-formatting)
```python
foo = Foo(
[
(0, 1),
(0, 1),
(0, 1),
(0, 1),
],
[],
)
```

Config file
```
[style]
continuation_align_style = fixed
```
