Repro:

• From the Hierarchy, right-click and start typing the name of the Component you wish to invoke
• As the user types, the list of creatable options is filtered, which is correct
• Press the down-arrow on the keyboard

Observed:

• The available options are not preselected. The cursor does not leave the text input field

Expected:

• Pressing down on the keyboard should preselect the first item on the filtered list. Pressing down subsequent times, should move down the list

Notes:

In most common quick-search tools - Window Start, or Mac Spotlight being obvious examples - the user is able to select from the filtered list. In Unity's new Create menu, this is not the case, which is quite jarring (in fact, users can select from the filtered list using only the keyboard, but they must press tab first. This is uncommon, and discoverability is poor).

We should follow the prevalent HMI convention here.
