migration_diff for LONGTEXT create TEXT since v5.x

[infoliv]

Since Migration 5.x, when I do the following steps :

1. I create a table test using phpmyadmin with 3 fields :

• id INT AUTOINCREMENT
• title VARCHAR (255)
• description LONGTEXT

2. I create a migration file with bin/cake bake migration_diff CreateTest

This generates the following migration file CreateTest.php :

use Migrations\BaseMigration;

class CreateTest extends BaseMigration
{
    public bool $autoId = false;

    /**
     * Up Method.
     *
     * More information on this method is available here:
     * https://book.cakephp.org/migrations/5/en/migrations.html#the-up-method
     *
     * @return void
     */
    public function up(): void
    {
        $this->table('test')
            ->addColumn('id', 'integer', [
                'autoIncrement' => true,
                'default' => null,
                'limit' => null,
                'null' => false,
                'signed' => false,
            ])
            ->addPrimaryKey(['id'])
            ->addColumn('title', 'string', [
                'default' => null,
                'limit' => 255,
                'null' => false,
            ])
            ->addColumn('description', 'text', [
                'default' => null,
                'limit' => 4294967295,
                'null' => false,
            ])
            ->create();
    }

    /**
     * Down Method.
     *
     * More information on this method is available here:
     * https://book.cakephp.org/migrations/5/en/migrations.html#the-down-method
     *
     * @return void
     */
    public function down(): void
    {
        $this->table('test')->drop()->save();
    }
}

And then, when I try to migrate that migration file, the description field is no longer LONGTEXT but TEXT.
