If the user is using the Transform a Layer tool on a Paint Layer then hides and unhides the layer, it remains hidden.

Reproducible: Always

Steps to Reproduce:
1. Add a Paint Layer and paint a stroke on it.
2. Use the Transform a Layer tool [Ctrl + T] to manipulate the layer in some way.
3. Click the visibility icon on the Paint Layer to hide it.
4. Click the visibility icon again to unhide it.
5. The layer remains hidden.

Actual Results:  
The layer stays hidden, even if the layer icon says it's visible.

Expected Results:  
The layer should become visible again if the visibility icon is active (eye is open).

If you don't manipulate the Transform a Layer tool in step 2, the layer hides and reappears deselected when toggling the visibility. It would be better if the layer was in the same state as the user left it when it reappears; the Transform a Layer tool should still be selected.
