Structure void blocks, breakable and placeable while in survival mode.

So, building a world with various different maps (parkour, pvp, skywars, etc) And /give myself a structure void block, switched over to survival mode to test if I can place blocks on the outside of it and found out I can break and place these blocks, while in survival mode, typically this isn't supposed to happen right? I just updated my game a few days ago to the recent 1.21.22 version. I found this on accident because I've used these blocks before and they never did this. 

My video exceeds attachment limit, here is a short yt clip of this bug:
