[Combobox] Cannot focus last remaining item in multiple selection mode via keyboard

[halljus]

Description

When I remove all but one item in a multiple selection Combobox using the keyboard, I expect to be able to focus (and remove) the last one, but I am unable to do so (arrow keys do not focus the last remaining item).

Steps to reproduce

1. Go to https://sparkui.vercel.app/?path=/docs/components-combobox--docs#default-1
2. Focus the input
3. Press Left Arrow twice to focus the "To Kill a Mockingbird" selected item
4. Press Delete to remove the selected item
5. Press Tab to focus the input again
6. Press Left Arrow

I expected it to focus the last remaining selected item ("War and Peace"), but it doesn't seem to move focus.

Thank you. There has been huge changes to Spark recently (only 1 developer remain, and a few contributors).

I can reproduce the bug, so it will be taken care of once Carousel and ScrollingList components have been released.

We have tons of issues on Combobox. We plan to replace it with Combobox and Autocomplete from Base UI, with Spark UI styles on top.
