linkStyle stroke attribute is not being rendered in htmlwidget

[alforj]

While the linkStyle stroke-width attributes are being rendered correctly in the example below, the stroke (color) attributes are not. All edges remain black when, according to the linkStyle, they should be red, blue, and green respectively. Using DiagrammeR_0.5.

DiagrammeR("graph LR;
A-->B;
C-->D;
E-->|This is the text|F;
linkStyle 0 stroke:red,stroke-width:2px;
linkStyle 1 stroke:green,stroke-width:4px;
linkStyle 2 stroke:blue,stroke-width:6px;")

Sorry, searched for linkStyle and didn't see any hits but just saw #81 and it looks like this may fall under that issue globally. Closing.
