Hello,

I have checked that issue on the default Storefront theme and there is the same issue – https://monosnap.com/file/7rVBJ7xbMAsq8qeORnBxBqiUBfh0N4 most likely the issue in your gif because for example, this one works well – https://take.ms/f8DEi and in our theme too – https://take.ms/eNrES

So this is not something related to our theme because as you see on the default theme the same issue.

Kind Regards
