[Problem/Bug]: Shift and Enter key doesn't trigger KeyDown and KeyUp

[pushkin-]

What happened?

I have a KeyDown and KeyUp handler that is trying to detect hotkeys. I have some hotkeys with the Shift key. When the Shift key is let go of, I want to trigger the key up and send a message to my webapp to handle the hotkey.

Howevver, the Shift key being depressed doesn't trigger the KeyUp event.

So when I have a hotkey like ctrl+alt+shift+e, if the shift key is the first key that's let go of, we don't detect it and instead think that the hotkey is ctrl+alt+e (once one of the other keys is let go of). So I need to let go of one of the other keys first for the hotkey to get triggered.

Similarly, I have a hotkey with chords, e.g. ctrl+a shift+b. We can detect ctrl+a fine, but shift+b isn't detected.

Also, I observered the the Enter key also doesn't trigger the keydown/up events.

Passing --enable-features=msWebView2BrowserHitTransparent to the webview2 control fixes the issue but then it also breaks other keys. So for example, tabbing between fields is now broken. It's like I have to handle it myself and send it to the webview2 control? Not sure.

Similar to this issue, though not quite the same #2245
