ComboBox does not properly support Voice Access

### Description

When using a combo box, Voice Access is not able to find the box to click/expand based on the selected value.

### Reproduction Steps

Create a new WPF project, and add a ComboBox with some items in it.

```xaml

```

Run the application and start Voice Access. "item 3" will be selected by default.

### Expected behavior

Because "item 3" is selected, saying "click item 3" should click and thus expand the combo box.

### Actual behavior

Voice access says "We can't find item three. Please try again."
