keepSuggestionsOnSuggestionSelected property
If set to true, the suggestions box will remain opened even after selecting a suggestion.
Note that if this is enabled, the only way
to close the suggestions box is either manually via the
SuggestionsBoxController or when the user closes the software
keyboard if hideSuggestionsOnKeyboardHide is set to true. Users
with a physical keyboard will be unable to close the
box without a manual way via SuggestionsBoxController.
Defaults to false.
