The code detects this as an error but intentionally does not report it
because in other cases a warning is already issued and I did not want
to re-issue the warning again. I'll dig into this more to see why it
is not issued the first time in this case.
However, this should *remain* a warning to be consistent with existing
code. When a class extends another non-abstract class and there isn't
an interface involved then it's only a warning. We should fix this in
PHP 8.0 for all cases.
