Horse in glass issue

[ChiefCrazyCow]

Drew was able to tp his horse to him while standing against glass panes, and then he rode the horse and it let him through the glass pane... is this an issue?

I think this happens, when you tp the horse, it is standing on the same block as the glass pane, and it might not be able to recognize that the glass pane is there, since the horse was loaded in the map (tp'd) in that exact spot. Not 100% sure though.
