Dismounting a horse with a fence on the player's right leaves the player on the wrong side of the fence

Current Behavior, 1.11:

Dismounting a horse next to a fence / glass pane / iron bars, with the fence on the player's right, places the player on the other side of the fence.

Original ticket

When travelling on a minecart heading east/west, with a fence (or glass pane, or iron bars etc.) to the north, if the player exits the card they will end up on the wrong side of the fence. This also happens when travelling north/south with a fence to the west, and does not happen in the other two possibilities. It also doesn't happen with any full-sized block e.g. glass blocks. Reproduced on single and multiplayer (I discovered it while in a glass-lined tunnel underneath a lava lake... ouch)
