Edit: why that auto betting feature stops when i do switch up other tabs or browsers?
this is done on purpose - so that you control your balance (when playing for real money, this is very important), leaving the page, you may lose your entire balance and not know about it if the automatic game continues without your participation
I have not visited this gambling website till now. But I don't think there is any need to stop auto bet when switching to other tabs. Users make auto bets on their own will and without any force. You can also add stop loss to stop the auto bet once the balance becomes lower than a specific amount.
