Description

Steps to reproduce:
1.Run the ComboBoxBug2 project.
2.Open the dropDownList and select the first item "100001".
3.In the textInput, type in one letter or digit at the end. e.g. type in "a" so now the text in the textInput becomes "100001a" .
4.Press ENTER to commit.
5.Press backspace or delete key to remove "a" so the text now becomes to "100001" (which is the first item in the dataProvider).
6.Press ENTER to commit.
7.Click on the openButton to open the dropDown.

Actual Results:
The first item should be highlighted and selected since it matches the text in the textInput.

Expected Results:
No item is highlighted or selected.

Workaround (if any):
The bug does not exist when using an ArrayCollection of Strings as the dataProvider.
