Short description of error
With multiple NLA strips within an NLA track, when setting the current frame to within the range of one of the NLA strips, the animation of previous/following strips is not taken into account. Consequently, NLA animation only works correctly if starting the animation with the very first frame.

Exact steps for others to reproduce the error

  1. Open the attached file. Description: The cube is animated in the NLA editor. There is one track containing two strips. The first strip contains a translation only, the second strip contains scaling only.
  2. Navigate to frame 40: You see that the cube is being scaled but the preceeding translation that is taking place in the first NLA strip is ignored.

I expect to always get the same result when navigating to the same frame.

I can't reproduce this with current master (2.82, rB7213c42b6e55c55f14472dbb9440d4628122bec8). The reported inconsistency is no longer there, as no matter how you play back the animation, the location from the first strip is no longer applied after the strip ended. This means it always snaps back to the origin, which IMO is expected & correct behaviour.
