Combobox: prevent auto selection of the first element

[evra]

Bug

The first element in the combobox is preselected when user starts typing in the input field. When user hits 'enter' the value of the first element gets applyed and replaces what the user already typed in the input field.

Package Version: 3.0.0

Expected behavior:

On Enter the value of the first element should not be copied into the input.

Actual behavior:

On Enter the value of the first element gets copied into the input field

@evra We intend the combo box to select the first matching item and set it as the input value when the user presses enter. Is there a specific set of steps to reproduce your issue outside of this scenario?

@tomdye The following steps can be used to reproduce the behavior:

First Scenario:

A combobox has two elements: 'A' and 'B', empty selection is allowed. None of the elements is selected in the combobox.

1. User clicks on the input element
2. A listbox is shown (first element is automatically marked as selected in the list).
3. User types C
4. Hits enter
5. Combobox takesover the first element from the list (A) and not the C (expected)

Second Scenario

A combobox has two elements: 'A' and 'B', empty selection is allowed. B is selected.

1. User clicks on the input element
2. A listbox is shown (first element is automatically marked as selected in the list).
3. User deletes the input
4. Hits enter
5. Combobox takesover the first element from the list (A) and not the empty value

Scenario one has been addressed and fixed in the typeahead, scenario two is a larger discussion around deselection which is being tracked and discussed via #1655

Closing this as will now be tracked via #1655
