Filters not working intuitively

Maybe it is my misunderstanding, but with this data:

```
{
"a": {
"b": [{
"c": {
"d": {
"e": "foo"
}
},
"something": "bar"
}, {
"c": {
"d": {
"e": "miss"
}
}
}]
}
}
```

With the following query, nothing returns:

`a.b[*].c.d[?e == 'foo']`

But this does work:

`a.b[*].c.d|@[?e == 'foo']`

And in JSON Path (JayWay implementation for example):

`a.b[*].c.d[?(@.e == "foo")]` is the equivalent.

Is this intentional? they seem functionally equivalent but obviously are not. This fails in the playground (JavaScript), but also fails in the Java implementation.

Is this a spec issue? As designed? Common bug in all implementations? Where do we report something like this that seems to be prevalent across all of JMES?
