Add preblur event to v-select

[BNicoleSchmidt]

For our application, when the user types in search text then clicks away, we want to automatically select the search text they typed in. We are unable to implement this by listening to the search:blur event. We have added a search:preblur event that fires when the select loses focus and the search text is available via the search property. We do not want to receive the event when a selection is made. So if I choose an entry from the dropdown, a search:preblur event is not sent.
