[🐞] Combobox value should clear search on value selection

[Toeler]

Which package is affected?

Headless Kit

Describe the bug

When selecting a value in a combobox, the search is kept (despite not being visible). This results in the list maintaining the filter when it is next opened.

Reproduction

https://stackblitz.com/edit/qwik-starter-ketzj8?file=src%2Froutes%2Findex.tsx

Steps to reproduce

On a page with a Combobox control:

• Click into the input box
• Type a letter to filter the options (e.g. "a")
• Click on any of the options
• Click on the trigger to open the combobox

Expected:

• The full list to be visible
• The combobox input area shows the current value
• Typing in the combobox should start a new search

Actual:

• The previous search is still in the internal state
• The combobox input area shows the current value
• Typing in the combobox appends the current value (so the user actually has to clear the input)

Additional Information

Notes:

• There is also a similar issue when using the defaultLabel property or otherwise trying to pre-select a value, it also configures the search and so the first time the dropdown is opened it is pre-filtered to only that value.
