Another incongruity of lines/crescendos

Friendly observation:
Notice that lines have the ability to be diagonal or not. If one enables diagonality then adds a degree to a line, and then unchecks diagonal, the degree gets removed and the line is back to horizontal. This makes sense. The problem is with crescendo/decrescendo lines. It seems to me that these should follow the same behavior in that if the user allows diagonality and utilizes angles, only later to uncheck the diagonal quality, the line should revert to a horizontal level. This isn't the case: the crescendo/decrescendo will maintain its angle. Either this should change, or the line should retain its angle for a congruous approach to the diagonal quality. At least this is my opinion, and if it is agreed hopefully this aids in the smoothness for future versions.
