Querying for trusted on the inventory endpoint doesn't hit the index

On the inventory endpoint, trusted facts can be queried in two ways

inventory[] { trusted.extensions.foo = "bar"}

But trusted is also just part of the factset

inventory[] { facts.trusted.extensions.foo = "bar" }

For the most part the queries function identically. But using trusted produces the filter

WHERE ((fs.stable||fs.volatile)->'trusted' @> '{"extensions": {"foo": "bar"}}'

and using facts.trusted produces the filter

WHERE ((fs.stable||fs.volatile) @> '{"trusted" {"extensions": {"foo": "bar"}}}'

the latter filter, using facts.trusted can use the index while the first, using trusted cannot because the index is on only (fs.stable || fs.volatile) so that must be what is on the left side of @> operator.
