linkStyle link color doesn't work with flowchart-elk

[DanWillans]

Description

When I attempt to set the link colour in a flowchart-elk it doesn't work like it does with flowchart.

Steps to reproduce

1. Using this example

flowchart-elk LR
    A -->|link| B

    %% Define linkstyles
    linkStyle 0 stroke:#ff0000,color:red

will give this chart where you can see the line colour is wrong.

2. Using normal flowchart

flowchart LR
    A -->|link| B

    %% Define linkstyles
    linkStyle 0 stroke:#ff0000,color:red

Gives a graph like this where the line colour is right:

Have run into the same issue. It also doesn't respect subgraph styling if you have something like:

graph TD
    classDef COLORING fill:yellow, stroke:black, stroke-width:2px, color:black
    subgraph SG["Subgraph"]
      a-->b
      b-->a
    end
    SG:::COLORING

It seems to ignore both stroke and stroke-width properties. Only color property work for the label
