Dualscreen icons are out of the screen

Hey guys, small issue with unity.

I have a dualscreen setup, one screen with 1400x900 and one with 1240x1024. As you can see, one is slightly taller (1024 vs 900) than the other, the smaller one is on the left, the bigger one is on the right. I have some icons on my desktop, today, I clicked on "Organise desktop by name". Unity arranged the icons by name, but it somehow arranged some beneath the bottom left edge of the left screen (the smaller one).

My guess is, Unity uses the maximum height of both screens and uses it as the overall desktop height (and I see the Workspace Switcher does exactly that).

This is not a critical issue, but could be a source of confusion.
