Please study the GIF attached.

1. I want to select an edge of the yellow-beige path
2. I grab Direct selection tool and drag a frame over the edge — OK
3. I make it faster — still OK
4. I make it with my usual speed and get the marquee that has 0 height. It happens with me all the time! I don't fake it, I just automatically try to drag the less tall frame as possible, because sometimes I need to select quite a tiny segment. And when it happens — Illustrator selects nothing.

Well, this is wrong.
If you draw a rectangle with zero height — you would get it, right? Just compressed to a line.
Surely it HAS some intersection, Ai just fails to trace it for me.
I'd love to get it fixed.
