Issue with syntax (code) highlighting in markdown

[embano1]

I found a weird issue when using Golang and https://highlightjs.org/ syntax highlighting.
If I specify

```go
...

then code highlighting will not use the design as specified in hjsStyle = "<style>". Basically it will look like:

func test(i int) string {
   fmt.Println("test only")
}

If I do not hint "go" for highlighting, then the formatting style will basically work (and look like other code blocks) but does not cover 100% Go syntax.

Can you reproduce this behaviour?
Thank you.
