ComboboxListBoxOption: aria-selected="true" on highlight is the correct pattern based on WCAG pattern

Hi,

It's mentioned here that aria-selected="true" shouldn't be applied when the option is highlighted. However, looking at the WCAG authoring practices guide pattern, that is how it works.

WCAG APG Pattern

It shows how aria-selected should be applied on an option here.

Thanks
