uui-combobox: selecting with keyboard doesn't work in a async combobox

[arknu]

Which exact UI Library version are you using? For example: 1.0.1 - don't just write v1.

1.16.0

Bug summary

This page in the docs shows the bug:
https://uui.umbraco.com/?path=/story/uui-combobox--async

If I type something in the combobox and select it with the mouse, it works perfectly

But - if I type something and then select it with the keyboard (arrows and then Enter), it is not selected. It seems that somehow the items being async make keyboard selection not work.

This is also evident when using the component in the Umbraco Backoffice.

Expected result / actual result

I would expect selection to work regardless of how I select and how the data is loaded.
