I am not sure why, but despite rich = true I cannot seem to use inline css for the tooltip content. For example:

"<span style='color: red'>Tooltip</span>"

Does not work, but if I add this to my css:

.redText {
    color: red;
}

And then do

"<span class='redText'>Tooltip</span>"

It correctly works, why is this?
