[Combobox](Vanilla): First letter is not recognized

[jramke]

🐛 Bug report

When using the Combobox component from the vanilla-ts example the list is not updated when the first letter is entered in the input field. Instead the default items are rendered. After typing another letter everything works (also when clearing and starting with a new first letter again) until we focus away.

💥 Steps to reproduce

1. start the vanilla-ts example
2. type one letter in the combobox
3. notice that the default options are rendered instead of filtered by this one letter

💻 Link to reproduction

Open the combobox page in the vanilla-ts example

🧐 Expected behavior

I would expect it to filter the items also on the first input like its done in the docs example with react.

We don't maintain those vanilla examples, feel free to attempt a fix for them and open a PR if you can.

That's a shame but thanks for the clarification. I will try to take a look at it.

@segunadebayo I think this same issue is persistent in the svelte-ts example directory as well.

Same reproduction steps as above, except run the svelte-ts example

I also tried the nuxt-ts example and the same issue I believe.
