# Strange behavior of dashed lines with +(coord)

At the left side of the `vd`

nodes, the dashed lines overlap. The first case is lucky, that the lines and gap match, but in the second case, the gaps are filled by the overlapping line segments.

The coordinate calculations translate to:

```
(1, y) -- (-1 or -2, y) -- (1, y) -- (2, y)
```
