Can not select anything within WkWebView editor view of my MacCatalyst app when running on macOS 14 Sonoma.
Any selection gesture or command key fails to select anything in content editable WKWebView, so none of the Editor tools can be activated.
My application uses the nnhubbard / ZSSRichTextEditor WKWebView-based Rich Text Editor: https://github.com/nnhubbard/ZSSRichTextEditor. The app is built with Xcode 15.4.
The app is a Catalyst app that implements an editor view with a ZSSRichTextEditor WKWebView.
The problem does not occur if the the app is run in macOS 11, 12, or 13 (Catalina, Monterey, or Ventura.) The issue only occurs in macOS 14 Sonoma.
The following error message is logged whenever an attempt to select any text in the WKWebView content:
0x1359ecc18 - [pageProxyID=14, webPageID=15, PID=14,932] WebPageProxy::didFailProvisionalLoadForFrame: frameID=1, isMainFrame=1, domain=NSURLErrorDomain, code=18,446,744,073,709,550,614, isMainFrame=1, willInternallyHandleFailure=0
Without the ability to select text the editor (WKWebView) is useless since no editing tool can be invoked without a selection.
