error overriding method with different access levels in inheritors

Compiler version

3.3.1

Minimized code

3 Java files

public interface RunConfiguration extends Cloneable {
  RunConfiguration clone();
}

public abstract class RunConfigurationBase<T> extends UserDataHolderBase implements RunConfiguration {
    @Override
    public RunConfiguration clone() {
        return null;
    }
}

import java.util.concurrent.atomic.AtomicReference;

public class UserDataHolderBase extends AtomicReference<String> {
    @Override
    protected Object clone() {
        return null;
    }
}

Main Scala File

class MyRunConfigurationScala extends RunConfigurationBase

Output

Compile the code.
Observe compilation error:

.../src/main/scala/MyRunConfigurationScala.scala
error overriding method clone in trait RunConfiguration of type (): RunConfiguration;
  method clone² in class UserDataHolderBase of type (): Object has weaker access privileges; it should be public

where:    clone  is a method in trait RunConfiguration
          clone² is a method in class UserDataHolderBase

class MyRunConfigurationScala extends RunConfigurationBase

Expectation

The code compiles fine.
Note that it compiles with Scala 2 compiler.
Also Java compiler compiles fine a similar code:
MyRunConfigurationJava.java

public class MyRunConfigurationJava extends RunConfigurationBase {
}

Note that this is a minimised example from the Scala Plugin project.
I tried to extract another module to Scala 3 and got this error.
Java classes are from library (IntelliJ SDK).

For now, the workaround is to explicitly override the clone method:

class MyRunConfigurationScala extends RunConfigurationBase {
  override def clone(): RunConfiguration = super.clone()
}

I believe this is a duplicate of #18654 and is also fixed by the associated PR #18953
