Hi Dimo, thanks for the reply. Sadly, in the video, you clicked everywhere except
in between the up and down arrows, which is where I was noticing the strange issue. :)
On the demo page
in Chrome 27, click near the top of the down arrow, then keep moving your cursor up 1 pixel and click again. You should notice that your cursor is a few pixels into the area of the up arrow, but the click event is still activating the down arrow. The screenshot I attached is showing how far up the cursor can be but still register on the down arrow. I went to a separate computer with Chrome 27 to eliminate it being just my computer as well.
Basically, it appears that the "middle area" in between the up and down arrows will always register to the down arrow, while it seems it should obviously be split between the two arrows.
If you need any further explanation, let me know. Thank you.
