Mouse gesture recognition problem question

I registered the gesture “move to the right”(→) using mouse gestures, but this gesture is not recognized.
However, the action is executed when the gesture is “move up right”(→↑) or “move down right”(→↓).

Is there a technical limitation that prevents the recognition of a horizontal “right only” gesture in a single direction? Or is it a bug?

straight lines are hard to recognize for the algorithm used. (Although it should work if you don't use too many).
There is a undocumented way to make them work better (requires a current beta/alpha version):

Thank you, it worked well!
I was able to execute it by updating to the alpha version and setting the gesture name to "right".
Thank you very much.
