With enableManualInput parameter as "true" if I typed some caracters in the field, and then I try to click at any option but the first in the filtered list, component always pick the first.
How reproduce it:
It is happing at showcase. Choose rich:select option at menu. At "Select with manual input" field, type 'al'. Alabama and Alaska will show up in the list. Try click in Alaska (second option), Alabama will be select.
The same happens if you filter the list and select the option using arrows keys and press tab. Otherwise, it will work if you do that but press Enter in the end.
Change selectFirst parameter value has no effect.
It works in 4.3.0.M1 release.
Sorry bad english mistakes. If I was not clear, ask me to clarify.
