Describe the bug

Finding an Option from the Combobox List

• Keyboard users (especially those using AT) expect to be able to type the same character to navigate through all options starting with the same letter (example: type “S” multiple times to move through “South Carolina” followed by “South Dakota”, etc.)

Selecting a Combobox Option

• Combobox allows users to confirm a selection using either the ENTER key (which is good) or the TAB key (which is unexpected behavior).
• Additionally, the SPACE key (often used to confirm selections) only scrolls down the Combobox list.
