What did you do?

Play stream and take memory heap snapshots using chrome dev tools at different times

What did you expect to happen?
Memory heap to be stable

What actually happened?

Memory heap grows consistently for multi-period streams.
On mono-period streams, we dot not notice the same result.

Please find screenshots:

• Heap snapshots to illustrate inscrease of memory consumption:
  

• Snapshots comparison after 45 minutes
  

• Details and allocation call stack (based on v4.5.x) of retained objects
  

Please note that all objects (Text, Element, NodeList ...) are allocated in the same place.

Duplicate of #6070

I'm not sure this is a duplicate of #6070 since #6070 memory issue is related to SegmentTimeline and the one described in this issue is more generally related to multi-periods, and noticeably since at least v 4.2.x.

Reopening.

@bbert Can you test if it still happens with 4.8.1? Thanks!
