The systray gadget don't resize himself correctly here,
it seems to never resize at all, it always stay at a minimum size and the icons overflow on the right size.
As you can see from the shot above the mega and the dropbox (ugly) icons are overflowing the shelf,
they are also not clickable when outside the shelf.
The same when I place the gadget in a central position:
I'm on latest efl/e git, but the issue is present from a long time.
