Vertical Timeline Icon Container Duplicated

Describe the bug

The Timeline component has a slot for an icon, but it doesn't render correctly. This TimelineItem in a vertical timeline

<TimelineItem title="Flowbite Library v1.2.2" date="Released on December 2nd, 2021">
                    <svelte:fragment slot="icon">
                            <CalendarWeekSolid class="w-3 h-3 text-primary-600 dark:text-primary-400" />
                    </svelte:fragment>
                    <p class="text-base font-normal text-gray-500 dark:text-gray-400">
                        Get started with dozens of web components and interactive elements built on top of
                        Tailwind CSS.
                    </p>
                </TimelineItem>

gives this result

The component provides a container, it just doesn't render the slot inside the container for some reason:

More info in the repro.

I'm happy to put up a PR if the team agrees this is a bug, otherwise maybe I'm just missing something.

Reproduction

https://stackblitz.com/edit/sveltejs-kit-template-default-qsf68n?file=src%2Froutes%2Ftimeline%2F%2Bpage.svelte

In the first TimelineItem, we just add the icon to the icon slot, and it renders incorrectly. The "workaround", which is encoded in the docs, is to create another container div with the same exact classes. You can see that by inspecting the second timeline item in the repro.
