Opening layer control overlay, flickering issue

[ahmadayubi]

When hovering from the bottom to open the control overlay the map alternates between opening and closing the overlay.

This is probably due to the size of the hover-able area being greater than the height of a single control overlay item. It alternates between the mouse being on the map and on the control overlay "button" causing flickering.

This can be fixed by either increasing the size of a single control overlay item, or decreasing the size of the control overlay button itself.
