Raise a Request : "Assets object field" Combobox is missing appropriate roles and/or attributes

Issue Summary

The element "Assets object field" appears and functions like a Combobox but is missing the required ARIA role(s) and/or attribute(s).

Steps to Reproduce

1. Launch the URL
2. In the Portal select any service request such as (Get IT help, Desktop/Laptop support, Request new software, etc.) 
3. Keeping the screen reader on navigate to the "Assets object field" Combobox.

Actual Results

• users are not aware that it is a combobox hence role=“combobox” is suggested in expected results.
• In VoicerOver the label of input “Assets object field (optional)” is not announcing when input is focused
• In NVDA the currently selected option is not announced.

Expected Results

• Provide role="combobox" to the <input> field.
• The label  "Assets object field (optional)” should be announced by the screen reader.
• Currently selected option should be announced by the screen reader.
