My code used to work on iOS versions prior to iOS16, but it no longer does.
I am running iPadOS -not checked on iPhones.
A view based on WKWebView is supposed to show HTML files inside a keyboard extension. It is now not not displaying correctly and any Javascript will lock up the UI. Setting stringByEvaluatingJavaScriptFromString > evaluateJavaScript's completionHandler to nil fixes this, but Javascript is not run.
No errors, but blank space.
Any ideas?

Any page that has a JavaScript function named "top()" in it causes JavaScript to fail.
The function doesn't need to be called or even contain anything.
eg.
function top()
{
}
JavaScript just locks up.
This affects iOS17.2 and macOS 14.2
If occurs in Safari and any app using WKWebView
This is a critical bug that affects sites and apps in the wild. I suggest there is something very wrong with the Javascript engine in general if certain function names can cause such a failure.
Does anyone else have other function names that cause this failure?
