Fix: Delete 'stroke: black' from lollipop marker so it matches themes and edge paths

[yari-dewalt]

📑 Summary

Currently if lollipop markers are used they are hard-coded to have a stroke of black. This PR removes that so it will match edge paths' strokes and work correctly with, for example, the dark theme.

📏 Design Decisions

Removes .attr('stroke', 'black') from the lollipop markers.
