The "Apply PerfectMatch and lock" option does not transfer comments from old bilinguals
The "Use the original origin and status" option transfers the comments... but using this option is not acceptable if the PerfectMatched segments need to be marked as PerfectMatch.
The "Apply PerfectMatch and Lock" option should behave consistently with the other option and transfer comments as well...
Ideally, the new behavior should be optional, with default being consistent with current behavior (i.e. to NOT transfer comments), to not break existing workflows relying on current behavior.
