Getting extra edges in hvplot+networkx (hvnx)

Using this example from [here](https://hvplot.holoviz.org/user_guide/NetworkX.html#weighted-graph) when modified slightly, it results in extra edges being drawn.
#### ALL software version info
(this library, plus any other relevant software, e.g. bokeh, python, notebook, OS, browser, etc)
Python 3.8

#### Description of expected behavior and the observed behavior
Edge (c, d) should not be solid in this case, and Edge (a, d) (needs closer look to see) should not be dashed according to the logic. But the result show these extra edges which shouldn’t be there according to condition. Please have a look.
#### Complete, minimal, self-contained example code that reproduces the issue

```
# Here is the code
import networkx as nx
import hvplot.networkx as hvnx

G = nx.DiGraph()

G.add_edge('a', 'b', Polarity=0.1)
G.add_edge('a', 'c', Polarity=0.1)
G.add_edge('c', 'd', Polarity=0.1)
G.add_edge('c', 'e', Polarity=0.6)
G.add_edge('c', 'f', Polarity=0.6)
G.add_edge('a', 'd', Polarity=0.6)

elarge = [(u, v) for (u, v, attr) in G.edges(data=True) if attr['Polarity'] > 0.5]
esmall = [(u, v) for (u, v, attr) in G.edges(data=True) if attr['Polarity'] <= 0.5]

pos = nx.spring_layout(G) # positions for all nodes

# nodes
nodes = hvnx.draw_networkx_nodes(G, pos, node_size=700)

# edges
edges1 = hvnx.draw_networkx_edges(
G, pos, edgelist=elarge, edge_width=6)
edges2 = hvnx.draw_networkx_edges(
G, pos, edgelist=esmall, edge_width=6, alpha=0.5, edge_color='blue', style='dashed')
labels = hvnx.draw_networkx_labels(G, pos, font_size=20, font_family='sans-serif')

edges1 * edges2 * nodes * labels
```
