Don’t know about Brits or Australians but Kane Williamson would have done the same as Dhoni. 
As per the video shared above - Rahul Dravid talks (4:14s) about how all the Indian players felt that it was not in the spirit of the game too and agreed with Dhoni.
On the contrary former Brit captain Naseer Hussain thought Ian Bell was at fault and was a lucky lad to be given another chance (5:47s). Former Captain Michael Atherton echoed a similar view.
So, there you go, this is how Brits take decisions!
