* There is a massive issue with reverse negotiation and dynamic pipelines.
*
* Since we're not waiting for the pads of the previous stack to block before
* re-switching, we might end up switching sources in the middle of a downstrea
* negotiation which will do reverse negotiation... with the new source (which
* is no longer the one that issues the request). That negotiation will fail
* and the original source will emit an ERROR message.
*
* In order to avoid those issues, we just ignore error messages from elements
* which aren't in the currently configured stack
