Improve Seach Dex (/) suggestions.

When typing the first name of a contact they often don't show up in the suggestions (so the thing that drops down without clicking 🔍Seach all for …). But other contacts, that have similar but different names, do! That's weird.

Also, for a second or two, the suggestions keep bouncing around. It would be better if they kept their order in the suggestions list, as I keep clicking the wrong contacts, constantly.
