Thanks for an authoritative clarification on this Kilishan.
I first observed this happening with my own code that was returning only content destined for JavaScript, and then tried to disable as much of my code as possible and observed the toolbar... which appeared to also (consistently) exhibit the same failure-to-update problem as what my code has. Not being up-to-speed on CI, I did suspect my code, but after a lot of fiddling, still couldn't establish a reason why the toolbar was behaving in a similar manner.
Now knowing it should work, I'll have another look, and possibly try to strip out an example to demonstrate how my code has managed to break it.
