@ihor-sviziev I was hoping you could contribute a bit here, seeing as you wrote the code. If you have a chance, that would be great.

Hi @hostep,
It seems like this issue already fixed by #8765.

Ah right, I thought this issue was going to get auto-closed by that PR, but that didn't happen apparently.

Let me manually close it then.

Thank you again @chandru-199! 🙂
