Short description of error
strips data actions failure to copy when pasted into new scenes
Exact steps for others to reproduce the error
In VSE: add any strip and insert key-frames(in opacity for example), press CTRL+C for copy strip > open a new scene or other archive, pulse CTRL+V > in the copy strip does not have action data and keyframes.
Note in rBeaee2b411935: Fix T36263: Pasted strip doesnt have F-Curve keyframes from the original, this already mentioned:
Better method would probably be storing animation data in clipboard as well,
so we can copy animated strips even between scenes.
