Is it possible to use HTML in label formatter?

[rdatasculptor]

Life would be a lot easier if I was allowed to use HTML in label formatting like the way that is possible in tooltips :) Is there a way, or a hack of some kind that would make this possible?

As an example, let's compare formatting of labels and tooltips:

df <- data.frame(xaxis = c(1,2,3), yaxis = c(1,2,3), label= c("<span><b>hi</b></span>", "hello", "hey"))

# whithout proper dealing with HTML
df %>% 
  e_charts(xaxis) %>%
  e_scatter(yaxis, bind = label,
            label = list(show = TRUE,
                         formatter = '{b}'))

# with proper dealing with HTML
df %>% 
  e_charts(xaxis) %>%
  e_scatter(yaxis) %>%
  e_add_nested('extra', label) %>% 
  e_tooltip(triggerOn="mousemove|click",
            formatter = htmlwidgets::JS(
              'function(params){
        return params.data.extra.label;
      }'
            ))

As you can see, the label formatter doesn't know how to use HTML, whilst the tooltip formatter does. Is there a way to make label formatter behave the same way as the tooltip formatter?

Many thanks in advance!
