textInput.typeahead doesn't work with two-word items

[MKliesch]

When the selectable data are character strings with spaces in-between (e.g. "Zurich Enge", "Zurich Wiedikon"), autocomplete-suggestions are made while typing the first word, but after entering the space, the second word is no longer autocompleted and can't be entered manually either. Clicking on a suggestion in the drop-down menu works, but if the item of interest is not yet suggested, it can also not be selected.
