@KaelWD hello

Behavior looks the same even back on v2.0.0 and in v1.5.x. Can you provide an example where its working as intended, or are there possibly reproduction steps missing?

https://codepen.io/djaler/pen/yLaGQKx this is the same code but with 2.3.17

Also, more detailed steps:

1. Open autocomplete by click on it
2. Select any item
3. Click anywhere else to remove focus from autocomplete
4. Open autocomplete by click on it again
5. Press backspace first time -> search will be cleared
6. Press backspace second time -> autocomplete value will be cleared
