This is not a good fix, and might even be worse.

Ideally, the first item should not be focused when the overlay is opened with a pointer. The overlay itself should be focused. After this change, if you open the overlay with a pointer, and press arrow down, you’d expect the first item to get focused. But the second item receives the focus instead.

The behavior of our components is inconsistent, when opening the overlay with a pointer:

• Context Menu: focuses the first item and shows the outline (how breadcrumbs works before this PR).
• Select: focuses the first item but doesn't show the outline (how breadcrumbs would work after this PR).
• Menu Bar: doesn't focus the first item (so no focus outline either) – this is the behavior we want.

Thanks, I misunderstood the TODO comment. Will close this PR and implement a corresponding fix.
