I don't see how your solution is addressing the problem in any way.

@bizley your tests not correct: 1.when passed more than one attribute, then need check they together BEFORE call validateAttribute() because they using together to generate SQL i.e. error in ANY attribute can fail execution 2. you call validateAttribute() instead validateAttributes() i.e. skip check skipOnError and skipOnEmpty and it's fake test: https://github.com/yiisoft/yii2/pull/19409/files#diff-558153fc1165cfc96b7b9bef56fcf62d67f049ae2fec7165e77561040b9ce360R523 3. you not set required attributes property using in validateAttributes() https://github.com/yiisoft/yii2/blob/14369f0a517efed333d69d44fc84eb8f4a5b1907/framework/validators/Validator.php#L248 4. you ignore property $targetClass i.e. you fix generate invalid query in case like this: [['foo', 'bar'], 'unique', 'targetClass' => Model::class, 'targetAttribute' => ['foo_id' => 'foo', 'bar_id' => 'bar']],

As I explained in details already in my fix attempt for this issue I stand behind my version.
