Foreign key on different database

The following does not work:

**Using dolt sql:**
```SQL
CREATE DATABASE parent_schema;
CREATE TABLE parent_schema.parent(
id INT,
PRIMARY KEY(id)
);

CREATE DATABASE child_schema;
CREATE TABLE child_schema.child(
id INT,
parent_id INT,
PRIMARY KEY(id),
CONSTRAINT parent_ref FOREIGN KEY(parent_id) REFERENCES parent_schema.parent(id)
);
```

It produces the error:
> table not found: parent

But still creates a table without the foreign key:
```SQL
describe child_schema.child;
```
Produces:
> +-----------+------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-----------+------+------+-----+---------+-------+
| id | int | NO | PRI | | |
| parent_id | int | YES | | | |
+-----------+------+------+-----+---------+-------+

Am I missing something?

_Tried with dolt version 0.36.0 and 0.37.6._

PS: Yes, my example is very much inspired by #1104
