“Disable/Enable when add to cart” in Cart SideBar not working

Hey guys!

Recently there was an update and now on the product page when clicking “add to cart” the Slidebar no longer appears automatically. So, that “Disable when add to cart” button ended up being useless. I believe it is because the product page when added to the cart ends up reloading?

I recorded a video to make it easier to understand: https://www.awesomescreenshot.com/video/21874046?key=88e13b65655a02e326f5a03236832960

Thank you so much!
