slickgrid background and highlight problem

[lpatiny]

I have a problem with slickgrid when using the background color options in postrenderer like

if(this.event === 'postRender') {
    let Color=API.cache('ReactionColor');
    if (this.row.item.value && this.row.item.value.status) {
        let status=Color.updateStatus(this.row.item.value.status);
        this.renderOptions = {
            backgroundColor: Color.getColor(Number(status.code))
        }
    }
}

the problem is that in this case the highlight of the mouse hover (or click) is not visible anymore. Is there a way to make the 'over' / 'selected' background priority ?
