In the case of two nested IF statements, the IfStmt returns the wrong lineNumber

[chumobyte]

Describe the bug
In the case of nested IF expressions, the outer second IF expression fetches the wrong lineNumber, mistakenly taking the lineNumber of the first IF.

• The main code in sootbug.zip

    public static void main(String[] args) {
        Options.v().set_src_prec(Options.src_prec_class);
        Options.v().set_keep_line_number(true);

        String classpath = System.getProperty("java.class.path");

        Options.v().set_soot_classpath(classpath);

        String classPath = "org.example.IfClass";
        Scene.v().loadClassAndSupport(classPath);
        Scene.v().loadNecessaryClasses();

        SootClass sc = Scene.v().getSootClass("org.example.IfClass");
        SootMethod sm = sc.getMethodByName("print");
        Body b = sm.retrieveActiveBody();

        for (Unit u : b.getUnits()) {
            if (u instanceof IfStmt) {
                IfStmt is = (IfStmt) u;
                System.out.println("line:[" + is.getTags().get(0) + "]      " + is.toString());
            }
        }
    }

• IfClass

    public void print(int score, String name) {
        if (score >= 90) {
            String aaa = "";
            if (!name.equals("admin")) {
                aaa = name;
            } else {
                aaa = "mute";
            }
            System.out.println(aaa + ":A");
        } else if (score >= 80) {
            System.out.println("B");
        } else if (score >= 70) {
            System.out.println("C");
        }
    }

To reproduce
Steps to reproduce the behavior:

1. Attached is a complete Java Maven project demonstrating the bug (it can only run in a Java 8 environment). Open it using IntelliJ IDEA and run it directly to demonstrate the issue I want to convey.
2. After running the project, the following information will be printed:

line:[9]      if i0 < 90 goto (branch)
line:[11]      if $z0 != 0 goto r9 = "mute"
line:[9]      if i0 < 80 goto (branch)
line:[19]      if i0 < 70 goto return

Expected behavior
I expect the expression if (score >= 80) to correctly display lineNumber 17.
