Clearing inputted text via non-keyboard doesn't refresh list

[AzzaAzza69]

Reproduce:
Using the first dropdown on the demo page, type in:
ab
Then use either the chrome "x" to clear the text or mouse highlight the ab letters, right-click and select "Cut"

Problem:
The input box is now empty and the list shows "No results.". A subsequent keypress (like shift or backspace) will re-populate the list.

I guess using the oninput would be the "correct" way of handling both moue and keyboard entry.
