Debian Buster is "stable", it means that to avoid regression, only
critical patches are applies (security or grave bug).
So this patch won't probably be accepted by Debian release team.

This bug will be fixed in Debian unstable with Apache 2.0.48 and be part of:
 * next Debian 12 (~2023)
 * Debian backports for Bullseye
 * maybe Debian backports for Buster (buster-backports-sloppy)
