minecraft:glow_lichen with no faces specified is not shown by structure blocks with Show Invisible Blocks on

Closely relates to MC-225939 and MC-225955.

This is probably a wontfix since glow lichen cannot normally be placed in this configuration. However, it's still a case of an invisible block not being shown where invisible blocks are stated to be shown.
