I am trying to have a message box display after the modal is closed. The code for opening the message box is in the result promise handler. When close is called on the modal instance, the message box is displaying, then once the message box is closed, the modal is closing. After investigating, the issue appears to be related to the close animation. I have included a proposed fix for this issue that involves moving the promise resolution so it happens once the animation is complete.

Should investigate this only after #2724 is merged.

I will take a look at implementing this sometime in the next couple of weeks - this requires branching out the logic depending on a configuration value.
