Invalid column size during migration in Mysql Adapater

[Zaszczyk]

Expected and Actual Behavior

Actual behavior: I generate migration of MySQL table with column MEDIUMTEXT and get size=1 of this field
SQL DDL:

create table map
(
  id int unsigned auto_increment
    primary key,
  path mediumtext null,
  created_at datetime null
)
  charset=utf8;

Phalcon migration:

public function morph()
    {
        $this->morphTable('map', [
                'columns' => [
                    new Column(
                        'id',
                        [
                            'type' => Column::TYPE_INTEGER,
                            'unsigned' => true,
                            'notNull' => true,
                            'autoIncrement' => true,
                            'size' => 10,
                            'first' => true
                        ]
                    ),
               
                    new Column(
                        'path',
                        [
                            'type' => Column::TYPE_TEXT,
                            'size' => 1,
                            'after' => 'id'
                        ]
                    ),

                    new Column(
                        'created_at',
                        [
                            'type' => Column::TYPE_DATETIME,
                            'size' => 1,
                            'after' => 'path'
                        ]
                    )
                ],
                'indexes' => [
                    new Index('PRIMARY', ['id'], 'PRIMARY'),
                ],
                'options' => [
                    'TABLE_TYPE' => 'BASE TABLE',
                    'AUTO_INCREMENT' => '298483',
                    'ENGINE' => 'InnoDB',
                    'TABLE_COLLATION' => 'utf8_general_ci'
                ],
            ]
        );
    }

Expected behavior: Phalcon migration should ommit size with MEDIUMTEXT field. When I manually remove 'size' =>1 then migration works fine.
