Why does the JavaScript scroll() function behave in reverse?
Question
From this thread: Vertical Scroll down and scroll up in Selenium WebDriver with java
I understand that scroll(xpos, ypos) needs:
- positive value - scroll down
- negative value - scroll up
However, isn't it that in the Cartesian Plane, down is negative for y-axis?
If anyone can clarify, that would be great. Thanks!

I think, I have found a highly relevant reading and also proof:
Why is the origin in computer graphics coordinates at the top left?
And since browsers display through a monitor, the same applies.
