#141 Bring & Go in zgrviewer does not have any effect when nodes have a `tooltip` attribute

[Anonymous]

If I open this dot file with zgrviewer, Bring & Go works as expected:

digraph {
1 -> 2 -> 3 -> 4 -> 5;
}

However if I add a tooltip attribute on the nodes, Bring & Go doesn't work anymore:

digraph {
node [tooltip="blah"];
1 -> 2 -> 3 -> 4 -> 5;
}

What I mean is that left click has no effect whatsoever. Hovering on the node stills outlines it in red, but clicking on it has no effect. No stacktrace is printed on stderr.
The tool above Bring & Go (whose name I don't know) does not work either.

Tested with zgrviewer 0.9.0, graphviz 2.40 on NixOS (nixpkgs commit f607771d0f5).
Tested with zgrviewer 0.10.0 as well.

Likely an issue with reconstructing the graph's topology from the SVG file. tooltips must be having a side effect on this. I will investigate.
