FAComboBox with IsTextSearchEnabled doesn't search through the whole collection but only the visible items

[Kermel]

Describe the bug
When I fill the combobox with lots of items (let's say a list of world states (around 219 items) the IsTextSearchEnabled feature doesn't work correctly - it always offers only results from the part of the list which is currently visible when combobox is open - i.e. the first items from the list; if I open the combobox and scroll down, then the search will only match with items that I have scrolled-to but never the rest of the combo
(i.e. if I scroll all the way down to "Zambia", the search will not position me on Albania if I start typing "Al...")

Desktop/Platform (please complete the following information):

• OS: [Windows 11]
• FluentAvalonia Version [latest]
• Avalonia Version [e.g. latest]

(am I missing some configuration maybe?)

I see... OK let's wait if this gets some fix
