WORLDEDIT-3829 - Reported by AeSix

WorldEdit 7.0.0-SNAPSHOT;3997-ba8bde0 (from enginehub builds)
Spigot git-Spigot-f56e2e7-7fc66b2 (built 18jan2019) (1.13.2)
ProtocolSupport snapshot build 340 (With and without this plugin running, does not seem to be the cause)
Thought this should not affect WorldEdit at all, I am connected through BungeeCord.
Using 1.13.2 unmodified client.

reproduction:
create a sign. select the sign (and multiple other blocks), //copy, //rotate 90, //paste
The sign is placed in the rotated coordinate, as expected.
The sign is facing the original orientation not the proper, rotated, orientation.

I have been using WorldEdit for a day or so. Today I created a sign which needed to be copied, rotated and pasted. This did not work as expected. The clipboard rotated and pasted at expected coordinates, however the sign orientation remained fixed to that of the original sign.

I tested with a few other items, which do rotate orientation on //rotate. I'm unable to spend the time to test every orientation-based item. However, I tested stairs, chests, banners and signs. Signs seem to be the only item affected by this.

Suspecting ProtocolSupport could be a culprit, I removed and re-tested. I received the same results.

Additional plugins which may potentially be interferring:
ProtocolLib, EditableSign, Vault, LogBlock, PlotSquared, WorldGuard
(all reasonably up to date versions, where possible)

There is no error in the log from WorldEdit or any other plugin or the server.
