With my own posts using the RTE, yes.
I added a smilie to a post, then saved it.
Then I edited the post and added another smilie (the same one).
I then open the post to edit again.
Now, when I look at the smilie (this one:), they're all at different stages of their spinning cycle.
The same as we had on vB; all smilies would spin at the same time, regardless of when they were added.
IE9, using the RTE.
This is only when editing, so it's not a major concern, but I was surprised by the behaviour, since that's now how it works when live, so it might be something that needs to be looked at.
