No worries...
Couldn't find anything concrete online, but I know that EK told us awhile back they were banned... there's articles online saying that shipments of them have been seized at Dubai Customs, however those were multiples.
A few pax recently were surprised to be told they were banned on EK, they also told me that they had not had any issues so far transiting so my *guess* would be if it is just one for you, it may not be an issue.
However, to be sure you could try contacting Dubai Customs directly.
I too would like to know for sure so I can give pax the correct info.
