tooltip: Fix possible wrong placement

When showing a tooltip on the edge of a monitor, the tooltip could be wrongly
placed and be shown going from one monitor to the next.

This happened because the current_window wasn't set visible, and when it wasn't
the returned allocated size would be 1, hence wrong calculations.
