@kiranchavala ok. This is a very simple and isolated fix, so I will include it in 4.23 RC2.

[winterhazel]

@kiranchavala does this bug also happen in 4.20.3? I saw that the changed code also exists in branch 4.20.

@kiranchavala does this bug also happen in 4.20.3? I saw that the changed code also exists in branch 4.20.

I checked that 4.20 does not have the OS filter, so this bug is not present in 4.20.3.

Merging this to 4.22 and then forward-merging to main.
