Describe the bug

There is a bug with the keyboard control of the MultiSelect component. The keyboard navigation only partially works, as shown in the attached GIF. When the "chips" variant is enabled, I am unable to focus on individual checkboxes using the keyboard. I can select the parent checkbox that selects all options, but I cannot select individual options. The focus only highlights the parent element that wraps the individual checkboxes.

Steps to reproduce the behavior

Enable the "chips" variant on the MultiSelect component.
Attempt to navigate through the checkboxes using the keyboard.

Expected behavior

Using the keyboard, I should be able to control the entire component, not just a part of it. I should be able to focus on and select individual checkboxes.
