Autofocus appropriate button for dialogs that roll advantage/disadvantage by default

[etiquettestartshere]

With concentration advantage mode on, when rolling concentration from a chat card prompt, the roll config will appear as above, 2d20kh. However, NORMAL is highlighted, and hitting enter will roll 1d20. Hitting ADVANTAGE will now correctly roll 2d20kh.

Expected behavior would seem to me to be ADVANTAGE is highlighted, and will roll 2d20kh on enter press.
