Unfortunately, it's not normal these days. How old is your T14? It seems like it's becoming increasingly a problem for Thinkpads as well (e.g. https://forum.thinkpads.com/viewtopic.php?t=134241 )
And I don't think it's just a software bug - many laptops now don't offer S3 at all, some only after toggling a BIOS option. Even then, it's often buggy on Linux as well.
Certainly not because, if that's the implication. Maybe since then in time.
