Current behavior

microsoft.toolkit.wpf.ui.controls.webview control won't honor the Z index property of canvas element. If I add children in canvas element whatever be the z index, webview will be the topmost element.

What system are you using for testing? Does this happen with the same page on Edge/UWP with WebView?

Please try to complete the template, as it'll help us identify the context, possible causes and reproduce it easier.

AFAIK, this is expected; ie, uwp views (webview, xaml islands) are always drawn on top of any other UI. @azchohfi, to keep me honest

Is there a parameter we can use to pass KeyDown through the window? I have an application that goes fullscreen and uses ESC to exit, however the window cannot capture the keydown event because it's captured by the element.

Now i know that's expected behaviour, because people need to be able to interact with the webviewer, but is their a flag we can trip to allow keydown to:

Copy - Push keydown through element tree Passthrough - never handle keydown

Hi all, I was also facing this issue, is there any update on this thread? Possible solutions/workarounds? I have a ListView inside of my WPF application and I'm using XamlIslands to display win10 WebView (Microsoft.Toolkit.Wpf.UI.Controls.WebView) inside the list elements. When I scroll in the list view, the WebView goes over the top bar and covers the minimize/maximize buttons as well. This is not what I expect. What possibilities do I have to do not cover the top bar?
