Why doesn't the browser's back button work?

Question

1C-Bitrix

When you go to the product card to return to the previous page, you must press the back button twice.

Answer 1

Check if you are using the js window.history functionality, maybe some script adds the current page to the history.

Answer 2

If there is an online store solution, then look at the choice of a trade offer. If I don’t confuse anything, in the store from Aspro, when entering the detail, a click on the first TP was emulated. And as a result, history was rewritten.
