Bamboo mosaic texture does not have nodes

The bug

Unlike bamboo planks, the texture of the bamboo mosaic block does not contain any nodes (represented by the light horizontal lines found on regular planks). This results in the bamboo mosaic block looking unnaturally flat compared to the usual planks.

How to reproduce

1. Place bamboo planks
2. Place bamboo mosaic
3. Compare the textures

Expected results

The bamboo planks and bamboo mosaic blocks would both contain nodes.

Actual results

Nodes are completely absent from the bamboo mosaic texture.
