Describe the bug

This is a bug at the border of UX and a11y (keyboard navigation).

1. Here's a codepen to investigate - we have one item works and then a group of colors in our combobox

2. Type 'works' in the input and confirm with enter - the item was correctly selected:

3. Type 'red' or any item that exists in the subgroup - hitting enter doesn't do anything (hitting many times at the end of the video)

Real-life example - we have this case in lens for fieldlist - we can only select Records by pressing Enter as it's not in the group, the rest is impossible to select with pressing Enter:
