Reviewed by Tim Horton.
The callbacks for DispatchAfterEnsuringDrawing get processed at the end of the
transaction, after we've already told
the client that we've committed the transaction. In some cases, this can cause
them to be included as a separate CA
commit, and cause flickering.
This adds a pre-transaction check for a callback for
hideContentUntilPendingUpdate, and clears the reply id, so that we
re-attach the root layer as part of the main commit.
