Attempt any selection on an object with a "selection" key.

The following example works a s expected:

JSON
{ "foo": { "sequence1": 123, "bar": "baz" } }

JSONata
foo.bar

Result
"baz"

When the key is changed to "sequence", it fails:

JSON
{ "foo": { "sequence": 123, "bar": "baz" } }

JSONata
foo.bar

Result
n.value is not a function
