Confusing Tuplets

Tuplet notation is getting its direction (up, down, or horizontal) based on the note stem, rather than the note head. This is confusing to the eyes as notes cross from A to B on the treble clef, for example. The notes may be rising, while the tuplet line is declining. This is messing me up while playing, because my eyes are seeing a downward slope (from the tuplet), when I am supposed to be playing rising notes. I have attached a screenshot of the issue.

I recommend that tuplets should get their direction (up, down, or horizontal) based on the note head, rather than the note stem.
