Picklists in Primefaces version 7.0 may have duplicated code.

[tester2023]

This is a picklist question for Primefaces version 7.0.
In the picklist, moving left-to-right and right-to-left at high speed could result in duplicates.
Have there been such incidents in the past?
Please let me know if you have any solutions or alternatives.

Version 7 is quite old. Can you duplicate it on 13.0.0?
