Ugh. You Mojang guys are literally just replacing one bug with another. ;-;

What I expected to happen

Glass panes would trigger the cullface of the tops and bottoms of other glass panes of the same type, like they did on previous versions before the 1.13 snapshots, and also like they do on all other faces of the glass panes.

What actually happened

Glass panes don't trigger the cullface of the tops and bottoms of other glass panes of the same type, like they did on previous versions before the 1.13 snapshots, and also like they do on all other faces of the glass panes.

How to reproduce

1. Download and enable the attached resource pack that adds cullface to glass panes
2. Place a glass pane on top of another glass pane of the same type
3. Notice how Mojang refuses to completely fix this bug
