Any way to fix Sodium Stained glass bug in 1.20.1

Processing img orpfymgf0hkg1...

Has anyone found a fix or made a patch for Sodium 0.5.13 on Fabric? I've been searching for any kind of fix to make stained-glass work correctly but haven't been able to find anything.

And BEFORE ANYONE SAYS ANYTHING: I KNOW this gets fixed in Sodium .6 I KNOW. The mod pack is 1.20.1, a version incompatible with .6 and updating my game version is not an option at this point. I am looking specifically for a 1.20.1 fix.
