How to not apply parent tag's style to child ones?

I have following html:

<li> Some item <strong>here</strong></li>

I add style to li tag to give them bullet points:

let li = Style {
            $0.textTransforms = [
                TextTransform.custom {
                    return "• " + $0
                }
            ]
        }

Because of li is the parent for tags inside of it, that text transformation is also applying to strong tag. So my strong tag having a bullet point. How to avoid it?
