Jonas Jenwald 373230185a Unconditionally initialize the this._pageOpenPendingSet in BaseViewer._initializeScriptingEvents (PR 12747 follow-up)
With the code dispatching a "pageopen" event on the existing (general) `BaseViewer` event "pagesinit", in practice this means that the `Set` is always being created. Hence we can simplify the method overall, by always initializing the `this._pageOpenPendingSet` property.
