Cart button in navbar / container aligned right


I have the problem that the shopping cart does not open on the right-hand side when I click on the corresponding button, but within the menu. What is the error here?

The strange thing is: only in Safari (Mac & iOS) the shopping cart works properly. Not in Google Chrome, Edge, Firefox, … Of course, the cache was always cleared to be on the safe side.
