iOS WKWebView NavigationDelegate methods with handlers doesn't work

[slartus]

Describe the bug
Overridden methods in NavigationDelegate with handlers do not work.
If you override the method, for example, of checking the availability of navigation and allow navigation to any URLs, then there will be a blank page.
When you remove this method, the links open.

example code:

@OptIn(ExperimentalForeignApi::class)
@Composable
actual fun WebView(modifier: Modifier, url: String) {
    UIKitView(
        modifier = modifier,
        factory = {
            WKWebView(
                frame = CGRectZero.readValue(),
            ).apply {
                navigationDelegate = WKNavigationDelegate()
                loadRequest(
                    request = NSURLRequest(
                        uRL = NSURL(string = url),
                    )
                )
            }
        }
    )
}

class WKNavigationDelegate : NSObject(), WKNavigationDelegateProtocol {
    override fun webView(
        webView: WKWebView,
        decidePolicyForNavigationAction: WKNavigationAction,
        decisionHandler: (WKNavigationActionPolicy) -> Unit,
    ) {
        decisionHandler(WKNavigationActionPolicy.WKNavigationActionPolicyAllow)
    }
}

same behavior with certificate verification method:

override fun webView(
        webView: WKWebView,
        didReceiveAuthenticationChallenge: NSURLAuthenticationChallenge,
        completionHandler: (NSURLSessionAuthChallengeDisposition, NSURLCredential?) -> Unit
    )

I also encountered this issue in my WebView project and could not find a solution.

Hello! Thanks for Issue, you may try to use remember function to save a hard link to navigationDelegate:

val rememberedNavigationDelegate = remember { WKNavigationDelegate() }

See examples here: https://github.com/dima-avdeev-jb/issue-3843-ios-webview

I will close this Issue, but if you will have some related questions, of something goes wrong - please feel free to reopen it
