Subject: [PATCH] Ensure that the data is loaded, in the "GetPageJSActions"
 message handler

Similar to all other data accesses, note e.g. the "GetDocJSActions" handler just above, we need to ensure that a `MissingDataException` isn't propagated to the main-thread if this data is accessed while the PDF document is still loading.
