Menu Application: If list element is a link, the xDropdown-header-toggle drops to a new line and other weirdness

If a list element is a link and has list elements one step below it (so it opens and show the elements) the Dropdown button gets a line break which is should not get.

See the pictures attached.

Steps to reproduce:

In the default menu, "Take a Tour" is not a link and has list elements one step below it. The Button to open is in line directly behind the Text "Take a Tour" which is good.

When making "Take a Tour" a link, the button drops to the next line which is unexpected and not good.

Expected (fixed) behaviour:

It should be fixed that making such a element to an link does not change the positioning of the button, the button should stay in line behind the text.

Also some padding/margins around buttons seem weird and need to be checked
