Make Synchronize Time of Related Items work with Time Remapping
Tracing back from a Time Remapped PreComp does not work correctly.
Ae is not setting the cti to the time that corresponding to the remapped time when navigating there via the Tab-key
David Simons (Adobe) commented
Because Time Remapping allows a single time in the source item to map to more than one time in the layer (e.g. if you had time going forwards and then backwards, a given frame in the middle of the source would end up at two different times in the comp), there's no right answer for which frame to go to.
But if you are only slowing down and never going backwards it could do what you want. Is that your typical case?
