Mermaid rendering issue

I just created a C4Context diagram and when I try to change the default colours it keeps ignoring the fontColor parameter.

Create a block like this one:

	title Example
	System(object, "Sample object")
	UpdateElementStyle(object, $fontColor="white", $bgColor="lightgrey")

The font color of the System Context box should be “white”.

Instead it remains the default one.
