Comment 3 for bug 1358893

From my testing, it also shows the current layer if it is currently hidden. It doesn't toggle if it is already showing.

Steps to reproduce:

1. Create a new document.
2. Create 3 different layers and put an object in each one.
3. Open Layers, then hide Layer 1.
4. Click 'show/hide other layers' on Layer 1.

Actual result:

Layer 1 is showing, layers 2/3 are hidden.

Expected result:

All layers are hidden.
