Header customer menus bleed out of the viewport on certain viewport sizes

[EliasTatX]

On sizes small enough that the customer menu buttons in the header (user menu and mini cart) move close enough to the right side of the screen, the dropdown menu opened by clicking them will bleed out of the viewport, creating an option to scroll to the side and making some parts not visible without scrolling. Since this looks bad and also has the ability to interfere with tests if correspondingly sized viewports are in use this should be fixed.

Note 1: this applies to posters starting from v2.1

Note 2: to fix this I changed these dropdowns to be right aligned. This solves the issue but if this is undesired visually something else will have to be done

As of posters 2.2 this issue is still not resolved owing to the particularities of the dropdowns. Currently they offer both normal bootstrap functionality in the form of open and pin on click as well as hover functionality. Since popper uses JavaScript and is only called by bootstrap for positioning when the standard bootstrap action used this currently is tricky to sync with the added in hover functionality which currently will always display the dropdown in its default position due to being very simplistic
