This is often the case with font attributes. For example, which color does the b have in "color yellow color red (a + color green b)", or which size does it have in "size *4 (a + size /2 b)"? Given a base size of 12, does it have the size 48, 6 or even 24 (which could be seen as a combination)? The following are basic resolution rules, which will be followed consistently in the future. In general, the rules apply to all group operations.
