Hello @helmut-jacob, @arnaudroques, all,

It seems to be partially corrected (with the mentioned commit), the label is now present but there are some overlapping of labels, see example here:

@startuml
switch (decision)
case (a\na a\na a a)
    :a;
    ->X\nX X\nX X X;
case (b\nb b\nb b b)
    :b;
    ->Y\nY Y\nY Y Y;
case (c\nc c\nc c c)
    :c;
    -><back:red>Z\n<back:red>Z Z\n<back:red>Z Z Z;
endswitch

@startuml
switch (decision)
case (a\na a\na a a)
    :a;
    ->X\nX X\nX X X;
case (b\nb b\nb b b)
    :b;
    ->Y\nY Y\nY Y Y;
case (b\nb b\nb b b)
    :b;
    -><back:green>Y\n<back:green>Y Y\n<back:green>Y Y Y;
case (c\nc c\nc c c)
    :c;
    -><back:red>Z\n<back:red>Z Z\n<back:red>Z Z Z;
endswitch
