Sort Members doesn't sort methods of record classes

Create a record class for e.g. like this:
```
public record MyRecord() {
public void methodB() {
}
public void methodA() {
}
public void methodC() {
}
}
```
Then select `Source` > `Sort Members...` > `Sort all members` > `OK` in the menu.

Result:

Nothing happens. The Methods are not sorted as configured in the "Member Sort Order" preference page.

Expected result:

Methods are sorted as configured in the "Member Sort Order" preference page.

Reproduce the issue with the record-class example and the Source > Sort Members > Sort all members flow. Trace the Sort Members handling for record classes and compare it with the Member Sort Order preferences. Done means the methods are reordered according to the configured preference.
