Bug 229600 – WKWebView: cannot become first responder using focus() in JavaScript or native becomeFirstResponder() method

• Status: NEW
• Component: HTML Editing

[Daohan Chong]

For example, if we'd like to build a web based text editor, we'd like to automatically focus on the text input area in `UIViewController.viewDidAppear`.

However, we cannot build behavior like this using public API. For example, all these won't work:

- Calling `htmlElement.focus()` does nothing.
- `WKWebView.becomeFirstResponder()`

The community is trying to explore how to work around this missing feature: https://stackoverflow.com/questions/32449870/programmatically-focus-on-a-form-in-a-webview-wkwebview/48623286#48623286

This can be reproduced on iOS 13 to iOS 15 beta.
