functionality when the back button on the browser is executed.
When the back button on the browser is executed, quote data from a previous sate is being reloaded and committed to the quote.
Many users use browser buttons to navigate to and fro instead of clicking tabs/actions. So if we have a quote in State A move to State B then to State C . And the user clicks back on the browser in state C, the system takes us Stage B or Stage A based on if the previous stage was in config or commerce.
The reload that will occur is moving the data from State A to State B and committing the data automatically.
