Reviewed by Aditya Keerthi.

Try to zero in on cases where typing on the software keyboard fails to insert text in `WKWebView`,
by testing one of my current hypotheses that this happens when the `_asyncInputDelegate` is `nil`
when receiving calls to `-handleKeyEntry:withCompletionHandler:` and related methods.

Note that I'm throttling these log messages to a maximum of just one every 10 seconds, to avoid
spamming log messages when typing, if the device is in state.
