Half doors open when you press a button on servers

When i was trying to open an door on a server i cannot go through it. (servers register me as afk)

BTW: this issue is only solved for singleplayer, not for servers.
for us minecrafters we expect:

if the issue says solved, we can hop onto minecraft without the issue not like: hey something else has the same issue thats solved but on singleplayer, so lets say this is solved to!
