persistent dance emote bug?

Time: 5pm est
Frequency: always? Well it can be fixed. I'll explain this below.
World name: ultros
Character name: player1. nazli harr and player 2. Rika swiftpaw
NPC name:n/a
Monster name:n/a
Class/Level:50 war (in Odin armor) 50 sch
Party or solo:light party, but can happen when solo.
In-game time: before 6pm eorzea time
Area and coordinates:korem estate, goblet ward 2 plot 15 private chamber 1. (Was on the haukke mandor desk)
Steps:
1.have player 1 have unlocked any and all persistent dances. Player 2 must not unlock them or have them or completed the quest line/seasonal event.
2.have player 1 perform the Manderville dance
3.player 2 reported from his client that all player 1 did was sit even though the chat log stated I started doing an emote and was doing it on my screen.
4. I checked to see if they completed the 4 quests that award dance emotes. (/dance worked just fine)

Since they didn't do any of the quests, I suspect it could be resolved by unlocking the emotes. However the bug is that their client didn't show me as dancing when it should have regardless if they unlocked the emote. Can you please look into this.
Unfortunately they are on a PC so we don't have video of it on their end.
