Renaming an action strip in the Action Editor gets updated in the Outliner(View layer), but not in the NLA Editor.
One can verify what action and NLAtrack strips are linked to an object by looking at the Outliner.
I can rename a NLAtrack in the NLA editor and it gets updated in the Outliner.
I noticed that if I append("link"?) a copy of the "renamed" action strip back into the NLA object where an original exists, ... one of them becomes a red box. When I click on one, the one being clicked on turns green, while the other turns red (tried this on the same NLAtrack), the same vice-versa when clicking on any -- the one being clicked on always turns green, and the other turns red. The animation though still is unhindered.
^ let me know if this is expected, ... to me it looks like a bug (I tried to find a bugreport about it but couldn't.)
tested with simple blend file: 1 cube, 1 plane..
