Bug report

The ComboBox doesn't reset its default state when removing the selected items with Ctrl+A && pressing the Delete/Backspace button.

This bug is a regression from the 2018 R3 version.

Reproduction of the problem

1. Open this Dojo project
2. Select the ComboBox and enter "Hanari Carnes", then select the first element
3. Clear the value of a field in one step (press Ctrl+A then Delete/Backspace button). The dropdown of the ComboBox will open.
4. Select the first element in the list - "Vins et alcools Chevalier".
5. The dropdown closes and no item is selected

Current behavior

When selecting the first element in the list, the Combobox closes without adding a value to the ComboBox input.

Expected/desired behavior

When the "Vins et alcools Chevalier" value is selected , the value should be added in the ComboBox input and the dropdown should close.
Here is a Dojo demonstrating the correct behavior.
