Overriding deprecated fields does not result in an error

This code does not produce any error:
```php
<?php
class A {
	/**
	 * @deprecated
	 */
	protected static string $staticVar = 'staticVarInA';

	/**
	 * @deprecated
	 */
	protected string $var = 'varInA';
}

class B extends A {
	protected static string $staticVar = 'staticVarInB';
	protected string $var = 'varInB';
}
```
