Problem:
At the Service Desk Portal, the list of options from dropdown fields like Components, Priority, Impact, Select list (single value), Select list (multiple choices) is not accessible with a screen reader.

The environment used for the test:
Mac Osx default screen reader
Firefox 76.0.1

Steps to Reproduce:

• Create a default IT Service Desk Project area;
• Open a Firefox browser and reach the portal;
• Select <Report a system Problem>;
• Hit <tab> to reach any of the fields "Select a System", "How urgent is this" or "What's the impact".
• Hit <arrow down> to access the list of options.

Expected behavior:

• Screen Reader identifies that this is a selection field and say "Start typing to get a list of possible matches or press down to select." or "Text list, x items";
• Arrow down/up should read each option;
• Enter should select an entry and the reader should say the option selected.

Observed results:

• The screen reader does not read any option while navigating with arrow down/up;
• Start typing does not help, the Screen Reader does not read the available options;
• There is no mention when a value is selected. The user may select an incorrect value by accident.

Business impact

• Users with visual disabilities can not use the Service Desk Portal
