InconclusiveDimensionOperation: Symbolic dimension comparison 'b' < '2147483647' is inconclusive.
### Description

A simple code to reproduce:

```py
import jax
import jax.numpy as jnp
import jax.experimental.jax2tf as jax2tf
import tensorflow as tf


def f(a):
    return jnp.sort(a, axis=-1)


my_model = tf.Module()
my_model.f = tf.function(
    jax2tf.convert(
        lambda x: jax.vmap(jax.jacrev(jax.jit(f)))(x),
        with_gradient=True,
        polymorphic_shapes=["b, 3"],
    ),
    autograph=False,
    input_signature=[
        tf.TensorSpec([None, 3], tf.float32),
    ],
)
tf.saved_model.save(
    my_model,
    "test_model",
    options=tf.saved_model.SaveOptions(experimental_custom_gradients=True),
)

```


Output:
```
