Fence posts, as well as walls, glass panes, iron bars and torches connect to a number of non-solid blocks listed below. This probably results from the improved connectivity towards stairs but can't really be intentional.

The fact that signs and banners connect, kind of make sense? No more flying infront of fences!
But you are right, when signs are standing on the ground they should not attach. Otherwise they should
Can confirm (17w15a)
It's already marked as confirmed, no need to comment that anymore.
Oh god, attached sings can't connect either. I can't count how many furniture constructions that would break in my world.
It's been marked as fixed but it also affects vines, tripwire hooks and string.
Affects sugarcane, nether portal blocks, end portal blocks, and structure void blocks as well in case you want to add those to the list. It also affects dragon eggs, but I'm not sure if that really applies to this bug or not (dragon eggs don't really fit the trend here).
Okay, it seems fences didn't connect to dragon eggs in previous versions, so I think they are affected here.
Don't forget torches (rs and light) on this list.
Fixed for everything except nether portal blocks in 17w16a.
Also still affects pistons and sticky pistons in 17w16a and 17w16b.
Changed expected results from pistons: if it's retracted all sides are full, and as such it's logical that it connects, for extended the sides are the only ones expected not to attach, so to keep it clean the retracted pistons should not connect with their sides.
