When an Outline view is sorted by some column(s), the row order is not adjusted when the cells change their values.

This can be reproduced e.g. in debugger's Watch view.
To reproduce, use following class:

public class LazyVarSortTest {
    
    public static void main(String[] args) {
        System.out.println("Begin");
    }
    
    private static String get(String str, int waitTime) {
        try {
            Thread.currentThread().sleep(waitTime);
        } catch (InterruptedException ex) {
            return null;
        }
        return str;
    }
}

Add breakpoint to the line with System.out.println.
Define following watches:
get("a", 2000)
get("g", 2500)
get("f", 2000)
get("c", 4000)
get("z", 5000)
get("b", 7000)

Sort the "Value" column and start debug.
The watches are loading one by one, but the order does not change. The "Value" column ends up unsorted even though the arrow marks it as sorted.
