No idea if this was with intention or not but: In version 1.14 the Glass panes decides to connect to the sea lanterns instead of creating a clean row as it used to in the last versions.
Version 1.14 (Released):
(This includes all the different dyed panes and clear panes, used the gray ones so you could see it more clearly)
If it's intentional then I'm sorry for wasting time, just a detail I noticed. Thank you!
Edit: Sorry for the mistake I meant sea lanterns only.
