Seek doesn't work in some specific case

What steps will reproduce the problem?
- try to play a Live Manifest with options to rewind and forward (once chunks 
become available). In other words, a stream with an option to watch form the 
beginning while stream still is live.
- count of chunks in the manifest grows each time while live
- perform seek on position < available duration

What do you see instead?
Streaming continues from previous position.
