At the moment when your roll includes a modifier the DisplayResult component properly displays the modified total however there's no indication in the calculation that there was a modifier at play, it simply shows the dice rolled = total.

This is particularly noticeable when you roll a single die with modifier. For example Roll('1d20', { modifier: 3 } results in "16 = 19" (when the die roll is 16 which is mathematically nonsense at best and also confusing.

It would be preferable to display some notion of the modifier eg "16 +3 = 19"
