Anonymous class using a trait with asbtract method inside another class

### Apache NetBeans version

Apache NetBeans 26 latest release candidate

### What happened

Using anonymous class inside a class that uses a trait with an asbtract method causes a missing implementation issue on the wrapping class


### Language / Project Type / NetBeans Component

PHP

### How to reproduce

The issue can be reproduced just using the following code.
For simplicity I added both a test trait and a consumer test class in the same file

```php

No source file or test is named. Start by reproducing the diagnostic in the NetBeans PHP editor with the trait and anonymous-class example from the issue, then trace how abstract trait methods are checked for anonymous classes nested in another class. Done means the wrapping class is no longer reported as missing an implementation when the anonymous class implements the method.
