[datagrid] web client on macOS with touchbar: Attempt to scroll a DataGrid to the left side activates native Back navigation instead

[muknta]

Bug description

Chrome on macOS has a native navigation action on left swipe using two fingers at the available area.
This action is low priority in order to use other scroll views at the web page.

So if you have an active scroll, this native action would not be activated. But if your horizontal scroll view is at the left side, which means you cannot longer scroll to the left, the native back action will be activate on attempt to scroll/swipe to this side.

I suppose there's something wrong with loosing focus on the Flutter side.

P.S. We have this bug on our proprietary project, but I saw that your demo also reproduces that.

Steps to reproduce

1. open https://flutter.syncfusion.com/#/datagrid/getting-started
2. minimize the window, so a DataGrid wouldn't fit on your window
3. scroll DataGrid to the right
4. then try to scroll to the left, it immediately activates the Back navigation action

Hi @Gowtham-SF4769,
I highly appreciate your fast response.
Which device you're using? I am able to reproduce this issue on both MacBook Pro M1 and MacBook Pro M4 using touch bar, both have macOS 15.5.

BTW, the issue doesn't appear if I'm scrolling vertically at first, and then to the left without any interruptions.
But if I'm scrolling horizontally only, to the left will always cause the Back action.

Sincerely,
Mykyta
