The previous implementation for base selection relied on gr-autocomplete firing a commit event to set the public base property. This did not work for entering a value that does not exist as an autocompleted value -- `commit` events are fired only upon autocompletion. This implementation instead gets the base on confirm and adds it to the event detail. Bug: Issue 8412 Change-Id: I479d11fca62b14880243b2f2d71bff72085a92fc
