Program editor: don't seek too far when stepping to the next keyframe.

Fixes #10389.  When stepping to the next keyframe to the right, some
old code causes it to skip over the next keyframe if it is too close.
This code seems unnecessary, but it is left there for now (commented
out) in case a valid reason is discovered.
