Reproducible in Writer, Calc, Draw, or Impress: Go to View > Zoom... See that this menu entry, despite having a submenu has an ellipsis at the end. However, ellipses are conventionally an indicator that a command will open a dialogue. Thus, this is confusing. (There is also an actual Zoom dialogue which is located under View > Zoom... > Zoom... and uses the same UI string.)
