Hi,
We updated our EO.WebBrower version from 24.0.20 to 24.0.96 version and it seems to so that this breaks Material UI Autocomplete component. We have also tested newest version and similar problem exist also there. But first version where it is broken is 24.0.96 version.

There is two issue which doesn't work properly. When you select item from dropdown menu it is not anymore selected and other one is that when you click scrollbar then drowdown menu box is closed which prevent scrolling. However scrolling works properly by using keyboard arrow keys or mouse wheel.

You can easily reproduce issue by using EO tabbed browser and go to Material UI web page which contains Autocomplete components: https://v5.mui.com/material-ui/react-autocomplete/

You can compare functionality for example Chrome browser where selecting item from drowdown menu and scrollbar works properly.

I also tested react select component and similar problem occurs also there with tabbed browser.

I think this issue is related for that change:
"EO.WebBrowser
Fixed some input method does not work properly when WebView is activated through mouse/touch issue;"

Do you have any workaround how to fix this issue because I have tried rather many things.

Hi,
Thanks for your answer. You described first problem correctly but there is also another problem related to combobox scrollbar. If you try scroll items in combobox by using mouse click it close the whole menu. If you scrolling item by mouse wheel then it works properly.

Then I would like to also clarified that this is not only problem with MUI AutoComplete component this occur also React Select component which is similar combobox. Here is page where you can try it : https://react-select.com/home#fixed-options This first combobox also contains scrollbar so you can try to click that and noticed that it close the whole combobox menu in that case.
