Given the below code:

namespace Database {
  export type Table<T> = T;
}

// 'Database' generic shadows the namespace, but namespace is used in 'Database.Table'
export function test<Database, Table extends Database.Table<Database>>(
  database: Database,
  table: Table
): { database: Database; table: Table } {
  return { database, table };
}

the top level Database symbol has no references, this is incorrect as it is refernced in the extends Database.Table

Database (id: 0): {
  symbol_id: 0
  span: { start: 10, end: 18 }
  name: "Database"
  flags: ValueModule
  scope_id: 0
  references: []
}

In typescript the left side of Database.Table is resolved with SymbolFlags.Namespace

When TS uses SymbolFlags.Namespace, it understands that type parameters have SymbolFlags.TypeParameter, and automatically excludes them when resolving the left side of a qualified name.
