[USelectMenu] Label of selected item disappears with async search

[peterhijma]

Description

This problem (?) is happening in the latest v2 version as well as the latest v3 (alpha) version. I will explain by giving a link to the v3 docs of the async search (without internal search):

https://ui3.nuxt.dev/components/select-menu#without-internal-search

Then take the next steps:

1. Select any item
2. Search for something that will not include the selected item
3. The label of the input will not show the currently selected item anymore
4. If you the make sure the selected item is in the list of returned items, it will appear again

Search for random string. Note that the avatar is correct:

I actually got exactly the same problem in v2 when using :searchable with an async function.
