Styling Links Label Background

[flywire]

Describe the bug

Cannot set specific link label background color.

Only option is to customise entire theme in diagram using edgeLabelBackground

To Reproduce

Steps to reproduce the behavior:

flowchart
    A-->|test|B
    linkStyle 0 stroke:#ff3,stroke-width:4px,color:red,background-color:lime;

Expected behavior

Set lime link label background color (instead of default gray) using background-color based on https://github.com/mermaid-js/mermaid/blob/develop/src/diagrams/flowchart/styles.js#L74

This should be made easier

[jsalsman]

{
  "theme": "neutral"
}

Is the easiest workaround for this. (Under "Config" in the online editor.)
