Closes #4265

Lgtm thanks for the pr.

[wesleycho]

My only question here is whether we should null the model as well in this situation. Otherwise, I'm fine with this PR.

[chenyuzhcy]

The model is already undefined in this situation

LGTM - thanks for the high quality PR!

This might not be the place for this -- found this PR when trying to debug an issue with typeahead-editable in the latest release (0.14.3).

Any ETA on the 14.4 release? Couldn't find anything specific in the roadmap wiki. I use typeahead-editable="false" heavily to prevent users from entering garbage in certain dropdowns.

@kencaron, there will not be a 0.14.4 release. we are trying to get 1.0 out the door and the release will be very soon. If you need this right away, please feel free to pull master and build a SNAPSHOT version.

This will clear input with same match entered from popup also.
