Cannot reveal the launcher with the mouse when it's set to auto-hide

[Niclas Lockner]

As the summary says, the launcher cannot be revealed with the mouse when it is set to auto-hide.
Setting different reveal sensibility values and reveal locations have no effect at all. The launcher doesn't make an attempt at all to reveal itself.
This was not a problem until just recently when I installed new updates.
