Subject: [PATCH] Don't swallow `MissingDataException`s in the
 `Annotation.prototype.#setOptionalContent` method (PR 21313 follow-up)

Unless the entire document has been loaded, the dictionary lookups in `parseMarkedContentProps` may throw `MissingDataException`s and in that case we need to re-parse the current Annotation rather than ignoring the optionalContent.
