Description

When selecting multiple layers on the Layers View, all the corresponding elements on the selected layers are not displayed.

Steps to Reproduce

1. Add a node to layer 1.

2. Add 3 new layers (will refer to them as layer 2, layer 3 and layer 4).

3. Select layer 2 only in Layers View. Add a new node to layer 3.

4. Select layer 3 only in Layers View. Add a new node to layer 3.

5. Select layer 4 only in Layers View. Add a new node to layer 4.

6. Deselect Layers. All nodes show up on Layer 0 (the complete graph).

7. Select layer 1, layer 2 and layer 3. Only layer 1 node shows on the graph.

Expected behaviour: Expect all elements from all selected layers to be displayed on the graph.

Actual behaviour: Only elements from the lowest numbered selected layer is displayed when all layers are selected. Or select layers 2 & 4, all layer 2 & 4 elements show up. With layers 1 & 3 selected, those elements show up. With layers 1 & 4, those elements show up. It's to do with masking logic.

Reproduces how often: 100%

Additional Information

Occurs in v2.11.0 and v3.0.0 - rc1
