There seem to be several problems with this component and the JAWS screen reader:

• the type of the field (i.e. a dropdown) is not indicated
• the screen reader doesn’t find the values in the dropdown
• the JAWS screen reader didn’t select value for regardless of value after selecting it by enter

Overall, it worked better with the NVDA screen reader

However, we also noticed that the options of the Dropdown are not highlighted on WHCM (see also T290646 and T283065)
