Chrome is also rather aggressive in this regard and I find myself constantly battling this issue when trying to add places autocomplete to an input. A workaround that seems to work reliable though, is to place the autocomplete-input outside of the form element. That is clearly not always a feasible solution, depending on your page / form layout, but for OPs layout it should be straightforward. After the user makes a selection you usually continue by dumping the json result into another hidden input anyway.
