when using star in the select of a subquery, the columns aren't available to queries making use of the subquery

Notice that user.id is used in the select of the limit subQuery in the working example. In the one that errors user.star() is used in the select of the limit subQuery.

Works

sql.define({name: 'user', columns: ['id','name','email', 'lastLogin']})
var limit = user.subQuery('limit-users').select(user.id)
limit.toString() // (SELECT "user".* FROM "user") "limit-users"
sql.select(limit.id, sql.constant(true).as("c")).from(limit).toString() // SELECT "limit-users"."id", TRUE AS "c" FROM (SELECT "user"."id" FROM "user") "limit-users"

Errors

sql.define({name: 'user', columns: ['id','name','email', 'lastLogin']})
var limit = user.subQuery('limit-users').select(user.star())
// ALSO results in error: var limit = user.subQuery('limit-users')
limit.toString() // (SELECT "user".* FROM "user") "limit-users"
sql.select(limit.id, sql.constant(true).as("c")).from(limit).toString()
