I have the following example, where i want the partial derivative index be raised up by metric, but eliminate_metric does nothing:

```
{\mu, \nu}::Indices(position=independent).
\partial{#}::PartialDerivative.
g_{\mu \nu}::Metric.
g^{\mu \nu}::InverseMetric.
g_{\mu}^{\nu}::KroneckerDelta.
g^{\mu}_{\nu}::KroneckerDelta.
g_{\mu \nu}::Depends(\partial{#}).
g^{\mu \nu}::Depends(\partial{#}).
```

```
expr:=g^{\mu \nu}\partial_{\nu}{A_{\mu}}.
eliminate_metric(_);
```

This results the same expression. Is there a way to raise up partial derivative index?
