@buyaa-n is there any action required to get this fix bundled with .NET 8?

I think it's same as runtime porting, let managers know and agreed with porting, create a backport with /backport to release/8.0, fill in the description, I believe then need to send out emails to tactics for approval. CC @carlossanlop
