[Problem/Bug]: Alt + Shift + S Shortcut not being passed to hosted components

[banushi-a]

What happened?

In our WPF application with WebView2 hosted portions, Alt + Shift + S shortcuts seem to be captured in WebView2, causing the web application to not receive them.

In Chrome, these shortcuts function as expected. In Edge, we see a Visual Search pop-up, which we assume is related to the underlying issue.

Importance

Moderate. My app's user experience is affected, but still usable.

Runtime Channel

Stable release (WebView2 Runtime)

Runtime Version

101.0.1210.39

SDK Version

1.0.2535.41

Framework

WPF

Operating System

Windows 11

OS Version

262000.8037

Repro steps

In a WPF application with WebView2 hosted activities, Alt + Shift + S doesn't work in the WebView2 activities. All other Alt + Shift + Letter combos correctly result in a response.

Expected behavior is for these shortcuts to work properly.

Repros in Edge Browser

Yes, issue can be reproduced in the corresponding Edge version

Regression

Don't know

Last working version (if regression)

No response

I can also reproduce in 148.0.3967.70, tested via running window.addEventListener("keydown", console.log, { capture: true }) in the top window and pressing the chord.

It seems to be a conflict with the visual search feature, which uses the same shortcut. If its disabled via GPO in Edge (or always disabled in WebView2 it seems) the feature doesn't run but the keypress is still consumed.

I can see it trigger the AcceleratorPressed event on the CoreWebView2Controller, but even setting IsBrowserAcceleratorKeyEnabled to false in that handler doesn't solve the issue, and the JS never gets the event.
