Describe problem (what you were doing; what happened; what should have happened): When sorting inventory by Name, an fps hit is incurred. When sorting by amount or by mod, this does not occur.

yes im also seeing this on minecraft 1.20.1 . if im running a s table 120 fps, then click sort, it dips down to 80 frames for a second or two before jumping back up.
