This works fine on 4.2.0, but is broken in 4.3.0

Expected behavior After selecting a value for an autocomplete, I should be able to enter something else in the field or use TAB to goto the next field

Actual behavior After selecting a value the autocomplete-field becomes inresponsive. I'm not able to type anything into the field, nor to exit the field using TAB. The only way to change the content of the field is to press arrow-down to open the list.
