There is unexpected behavior with roll highlighting (red/green box around the result of an inline roll) when using the "keep highest" or "keep lowest" functionality. If I make the following inline roll: [[{1d20, 1d20}kh1]], I would not expect that a result of 1 on the die not used would highlight the roll, however it does. Here is a screenshot illustrating what I mean. In the above case the 6 was used and the 1 was not, however the output is quite confusing because a 6, while a terrible roll, is not a critical failure. It would be much clearer to only use roll highlighting on the actual result of the kh/kl syntax, rather than all dice used in the roll.
