CylinderBufferGeometry with Multiple Materials fails (on Firefox)

Bug on CylinderBufferGeometry with Multiple Materials (on Firefox)

Create a geometry using CylinderBufferGeometry. Then use in a mesh with 3 different materials for torso, top, and bottom.

In Firefox browser (v62, Win10) the mesh will not display properly with missing parts. Other browsers (Chrome, Edge, IE) all work correctly.

Originally seen with canvas textures but seems to be a problem even with the Normal material.

Regular original CylinderGeometry is fine. In the fiddle you can see the problem with the Buffer on the right cylinder:
