Multiple WebView2 control have focus sometimes.

[YuuukiA]

Description

I'm using multiple WebView2 control in WPF application.
It seems that multiple WebView2 control have focus sometimes.
Would you please check it?

Version
SDK: WebView2 1.0.1518.46
Runtime: Microsoft.Web.WebView2 1.0.1518.46
Framework: WPF, .Net6
OS: Win10

Repro Steps

I made a simple app as the following.

1. Launch app.
2. Press "F2" key.
   --> Sub window is shown.
3. Set cursor to "Search" Textbox in the following order.
   View1 -> View2 -> Sub window -> View2
   --> Cursor is blinking in both View1 and View2.

<Window
    x:Class="WpfApp17.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:wv2="clr-namespace:Microsoft.Web.WebView2.Wpf;assembly=Microsoft.Web.WebView2.Wpf"
    Title="Test"
    MinWidth="250"
    WindowStartupLocation="CenterScreen">

    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>

        <wv2:WebView2 x:Name="View1" Source="https://docs.microsoft.com/en-us/" />
        <wv2:WebView2 x:Name="View2" Grid.Row="1" Source="https://docs.microsoft.com/en-us/" />
    </Grid>
</Window>

Code behind

using Microsoft.Web.WebView2.Wpf;
using System;
using System.Windows;
using System.Windows.Input;

namespace WpfApp17
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        protected override void OnKeyDown(KeyEventArgs e)
        {
            base.OnKeyDown(e);

            if (e.Key == Key.F2)
            {
                var w = new Window();
                w.Width = 500;
                w.Height = 400;

                var webView = new WebView2() { Title = "Sub window" };
                webView.Source = new Uri("https://docs.microsoft.com/en-us/");
                w.Content = webView;

                w.Owner = this;
                w.Show();
            }
        }
    }
}

Hi,
We have looked into this issue and confirmed that it is caused by WPF's FocusManager(it restores the recent focused window but does not work properly in this scenario). We are still looking for a proper fix and I'll tell you if any update.

Currently you can disable this feature by overriding Window_Activated:

<Window x:Class="WpfApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="450" Width="800"
        Activated="Window_Activated">
    <!-- WebView2 Controls -->
</Window>

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void Window_Activated(object sender, EventArgs e)
    {
        // Set focus to the window itself when activated
        Focus();
    }
}
