Hello,
I'd like to report a bug I found in Material UI's Autocomplete component.
Test it here: https://azurealstn.github.io/autocomplete
Source code: https://github.com/azurealstn/autocomplete
Issue:
The variable top100Films used in the options property contains English labels, which is fine. However, when searching with Korean text ('스') and using the mouse wheel to scroll, then clicking an item, the scroll position resets.
[Detailed explanation]

Enter '스' in the input and scroll down
When pressing (but not releasing) the mouse on the ComboBox, the scroll resets
When releasing the mouse, the item is selected from the reset scroll position

Is there any way to solve this issue?

• Browser: Chrome

Interesting 👀

@azurealstn Korean uses IME input like Japanese/Chinese right? It may not be related to this issue, but in your gif you're just pasting in the characters?

@azurealstn As far as I can see, when 스 is in the textbox, the popup immediately shows no results even though it seems like there should be some matches?

🤔 My first thought is that it could be the default filtering logic here doesn't handle Korean characters well and needs to be customized: https://mui.com/material-ui/react-autocomplete/#custom-filter

====
it's an IME input!
When copying and pasting text to select an item, the scroll doesn't reset.
However, when typing directly from the keyboard, the scroll resets.
As you mentioned, I'll try using the Custom filter option."

It seems the issue is related to IME input. Filter options don't seem to be working well either. Do you have any other approaches we could try?
