[Problem/Bug]: Position of select inputs not updating

[josago97]

What happened?

When deploying a select input, the dropdown takes the position of the last position where the element was, not where the input currently is. Furthermore, if you display the select and move the window, the display remains fixed, its position is not relative to the select input.

Importance

Important. My app's user experience is significantly compromised.

Hello,

Thanks for taking the time to file this issue. To accurately understand and triage this problem could you help us clarify what framework you are using for your app? For example is it Win32, UWP, WinForms, WPF, WinAppSDK, etc...

Also, are you using this API in your app: NotifyParentWindowPositionChanged. Its purpose is to make the parent window aware of window position changes.

I'm using Photino, this is the website and this is its Github repository.

I am not using that API and I don't know if Photino uses it. I'm going to put an issue in their repository to see if they are using it.

I am one of the maintainers of Photino. We have just implemented this call on WM_MOVE and WM_MOVING and validated that it is being called, however, the problem remains. We are currently using the WebView2 NuGet package version 1.0.1462.37. The link above is for a pre-release version where the method is part of a host object. We're implementing this on the controller object: https://learn.microsoft.com/en-us/dotnet/api/microsoft.web.webview2.core.corewebview2controller.notifyparentwindowpositionchanged?view=webview2-dotnet-1.0.1462.37 Please advise.

Any ideas why the API is not working correctly?

[MikeYeager]

We are loading the webview control from a Win32 native window in C++. We are calling NotifyParentWindowPositionChanged on both WM_MOVE and WM_MOVING in the event loop and have validated that it is being called. It appears to have no effect on the webview control.

@victorhuangwq @tochukwuIbeEkeocha I've been testing with other libraries and they suffer from the same problem. There are many posts reporting the bug, some even saying that it doesn't work well in Tauri either. Are you sure the API works fine?

.NET MAUI (It uses Microsoft.AspNetCore.Components.WebView.Maui)

AvaloniaUI (It uses Microsoft.Web.WebView2.WinForms)
