Decompile return within the if-else block inside try-except format code fail

[waaaagit]

python3.11

def test(a, b):
    try:
        if a/b:
            a=1
        else:
            a=2
    except:
        return 3
    return

def test(a, b):
    try:
        if a/b:
            a=1
        else:
            a=2
        return 0
    except:
        return 3
    return

The two cases above can be decompile correctly

def test(a, b):
    try:
        if a/b:
            a=1
            return 1
        else:
            a=2
    except:
        return 3
    return

def test(a, b):
    try:
        if a/b:
            a=1
        else:
            a=2
            return 2
    except:
        return 3
    return

The two cases above can't be decompile correctly
