[Bug]: "Tags with combobox" example inserts ComboboxContent twice

[JarvisH]

Reproduction

https://www.shadcn-vue.com/docs/components/tags-input.html#tags-with-combobox

Describe the bug

The official example of using a "Tags input" with a combobox inserts the ComboboxContent twice. Once via direct usage of <ComboboxContent /> and again via <CommandList /> which contains another instance of <ComboboxContent />.

This results in two wrapper divs containing identical roles and ids.

I should add, that simply removing the first instance of <ComboboxContent /> fixes the issue, but this necessitates adding :dismissable="true" to <CommandList />

Edit: :dismissable="true" messes with Firefox, the list no longer closes when using the tab key. To fix this sideeffect, I added tabindex="-1" to <CommandList />
