so am i, "How did you pinpoint that it was caused by CSS properties?"@qwwp Did you add breakpoints in these functions? -[CALayer setPosition:] -[CALayer setFrame:] -[UIView setFrame:] -[UIView setBounds:]

I found this solution by setting WKWebview's configuration or using xcode26 to build project self.webview.configuration.preferences.textInteractionEnabled = NO; maybe u can try it
