Sequencer animations using Skeletal Mesh Pose don't play properly if following another sequence with an animation using Keep State

The bug affects skeletal mesh animations when played in sequencer with AnimBP after another animation which was set to Keep State. This is a follow-up to [Link Removed].
Two animations now play correctly if played within the same sequence. If the second animation is played in a separate sequence, it will not be performed correctly.
This affects any animations, not just reversed animations as described in the original issue.
Characters have text comments over them in the level to make it simpler to understand which case is being observed.

This was reported and tested in 4.22 (CL-5035897). This was reproduced in Main 4.23 (CL-5091052)

1. Download and open the attached project
2. Press play and observe the behavior of two characters going to sleep and then getting back up from beds: the one marked as "Normal and reversed in one sequence" and the one marked as "Normal and reversed split into two sequences"

Results: The character marked as "Normal and reversed in one sequence" plays animation correctly. The character marked "Normal and reversed split into two sequences" animates incorrectly.

Expected:The character marked "Normal and reversed split into two sequences" should animate in the same manner as the one marked as "Normal and reversed in one sequence".
