Autocomplete menu had a bug that showed the same item more than once as
the user kept on typing. The issue is now fixed since the way the items
are closed is reworked and is solidly working all right.
The suggestions div has a certain amount of padding that create a div
kind of object when the entered content doesn't match anything, however
this was creating an issue for the settings page.
Fixed that bug by hiding that div when the settings page is opened
