wv2ScriptDialogKind

Identifies which JavaScript-dialog primitive the page is trying to open. Carried as the ScriptDialogKind argument of the ScriptDialogOpening event — the event only fires when AreDefaultScriptDialogsEnabled is False, so the application can implement its own dialogs. Mirrors the COREWEBVIEW2_SCRIPT_DIALOG_KIND enumeration.
