I have a view controller that is hosing a WKWebView. My view controller overrides buildMenu(with builder: UIMenuBuilder), and prior to the beta, this was called reliably. However under 18.2 beta 4, it is not called at all, despite no code changes on my part.
Things I've tried:
Ensured that my responder chain is set up correctly.
Walked through the debugger via a symbolic breakpoint on [UIResponder buildMenuWithBuilder:] to understand that the web view is the last object to get a buildMenuWithBuilder message.
Any feedback or commiseration would be appreciated.
