Example file that demonstrates the issue

SUMMARY
On graphs where the nodes have no shape (shape=none or shape=plain) the node labels disappear when zoomed in

STEPS TO REPRODUCE
1. Open the attached example file. (This is abstract.gv from graphviz with one line added: `node [shape=none];` )
2. zoom in and out

OBSERVED RESULT
The node labels vanish above a certain zoom level

EXPECTED RESULT
The node labels remain visible

ADDITIONAL INFO
1. The same file with the line `node [shape=none];` removed (i.e. as per the original file from graphviz) renders OK at all zoom levels
2. The point at which the labels dissapear seems to be at the zoom where one of them goes partly outside the window
