MacCatalyst WebView keydown events are not captured

[nicobarengo]

Description

On MacOS Ventura when using a WebView, key events are not captured so, for example using tab key to navigate between input fields is not working, also it's its imposible to read the keydown event from javascript.

Steps to Reproduce

1. Create a new MAUI App and add a WebView pointing to https://www.toptal.com/developers/keycode or any other website
2. Run the App in MacOS Ventura
3. Use tab key to navigate between fields and verify that are not captured.

I think this is how the implementation of WKWebView works on Catalyst, or a bug with it.

https://github.com/drasticactions/MauiRepros/tree/main/WebviewTestCatalyst

I wrote a .NET Mac Catalyst app (Without the MAUI UI) and loaded the same WKWebView type MAUI uses for its webview, and it operates the same.

Funny enough, they mention the same site as you.

Nothing can be done within this repo if this is a bug with WKWebView. That would need to be fixed by Apple.

Let's hope apple fixes this, because MAUI Blazor Apps will be the most affected.

Same issue, but in Blazor Hybrid: #12244

I've also confirmed that this is an issue with WKWebView on MacCatalyst, nothing to do with .NET or MAUI. I wrote an app with Xcode and Swift to directly repro this: https://github.com/Eilon/MacCatalystWebViewKeyboard/tree/main

And, sure enough, the exact same issue reproduces.

I'll see how we can contact Apple with this issue so that they can try to address it as soon as possible.

I filed a feedback issue with Apple with ID FB12076485 (I don't think it's publicly visible).

I'll update this issue with anything I hear back.
