Neither lsr::cohensD nor rstatix::cohens_d are affected by sorting order in comparison, however lsr::cohensD gives a reasonable warning:
calculating paired samples Cohen's d using formula input. Results will be incorrect if cases do not appear in the same order for both levels of the grouping factor
They also report different effect sizes for paired tests altogether, please see #49.

Thank you for your report.
I am fixing the issue of dependency on order.
Also I am adding a warning similar to the one reported by ``lsr::cohensD`
