WPF: ChromiumWebBrowser as child to ScrollViewer prevent focus of HTML elements

[robinwassen]

If you put the ChromiumWebBrowser as a child to a ScrollViewer the focus will start to misbehave.

Focus is lost if you left click a html element in the browser and it kind of works if you right click.

Steps to reproduce:

1. Add a ScrollViewer in the XAML
2. Add the ChromiumWebBrowser with a HTML document containing a text input as a child to the ScrollViewer
3. Try to focus the text input by left clicking in it

Expected outcome: The text input in the HTML document should get focus.

Outcome: The text input get focus for a fraction of a second and then loses it.

Pure C# workaround:

1. Add a event listener to MouseDown on the ChromiumWebBrowser
2. Add e.Handled = true in the handler to prevent MouseDown from bubbling

XAML:

<cefSharp:ChromiumWebBrowser x:Name="chromiumWebBrowser" MouseDown="chromiumWebBrowser_MouseDown"  Height="800"  Address="http://www.example.com" />

C#:

void chromiumWebBrowser_MouseDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
{
    e.Handled = true;
}
