Subject: [PATCH] task widget: Check if mouse is still over attached widget in
 aync show

This fixes issue #356. Using an approach similar
to what is implemented in other lain widgets (e.g:
calendar). That is, checking the mouse is still over
the target widget inside the `helpers.async` function
call in `task.show()`.
