Bug in GUI with graphviz 2.40

The output svg format changes with graphviz 2.40 and the GUI (left part with rewriting history) is broken. Attached the output of the two versions on the same input:

digraph G {
    node [fontname=Arial];
    ranksep=0.01;
    nodesep=0.04
    node_mod_0_0 [label="", fontcolor=transparent, color=transparent]
    node_mod_0 [label="init"]
    {rank=same; G0; node_mod_0_0}
    node_mod_0_0 -> G0 [color=transparent]
    node_mod_0_0 -> node_mod_0 [color=transparent]
    G0 [shape=box, label="G0", style=filled, fillcolor="#35FF5C"]
    node_mod_1_0 [label="", fontcolor=transparent, color=transparent]
    node_mod_1 [label="##end##", fontcolor=transparent, color=transparent]
    {rank=same; G1; node_mod_1_0}
    node_mod_1_0 -> G1 [color=transparent]
    node_mod_1_0 -> node_mod_1 [color=transparent]
    node_mod_0 -> node_mod_1_0 [color=transparent]
    G1 [shape=box, label="G1", style=filled, fillcolor="#FF3E47", peripheries=2]
    G0 -> G1
{rank=same; G1; node_mod_1_0}
}
