Samuel added 1.15 to the list of line spacing in the paragraph dialog in bug 85949, but unfortunately the preview in the dialog is now wrong as it isnt being rendered on what value is there in the dialog, but what entry is selected in the list, which it now has taken over the position of where 1.5 used to be.
Confirmed.
