#command ⇒ Object

The Page.javascriptDialogOpening event is handled on Ferrum's background CDP dispatcher thread, so raising there wouldn't reach the caller and would permanently kill that thread instead. The dialog is always accepted immediately from that thread, and the error (if any) is stashed here to be raised from the main thread the next time it makes a command round trip.

#ferrum_command ⇒ Object

Keep a handle to Ferrum's own implementation before overriding it below, so answering a dialog (see handle_javascript_dialog) can bypass our override.
