I have this weird glitch where I can jump through blocks but it only happens once I die in water so, when I died on the water I jumped on a block and it let me go through it but only for a second but it still took some hearts away from me. I'll say this again but ill make it better, So when I was on the water searching for a glowing squid I drowned lol so when I respawned I was just searching for another water source but then I jumped making me hit on the roof of a cave but instead of hitting the roof I went through the block in the roof of the cave, I saw this bug and so I tried it on a new world, I saw that it only happens when  you die on water or get killed by a drowned or just drown (ONLY HAPPENED IF YOU GET KILLED ON WATER) so the bug lets you go/jump through the block as I said and it can cause some trouble leading to deaths and item lose because you can suffocate on when you're inside the block ( extra: I play on iPhone SE with no mods and texture packs I only use bedrock, normal bedrock.) This glitch lets you go through a block or just 1 block it doesn't really let you walk through blocks but it could be considered as it does so the bug basically is that you can go through the block as long as you die in water ( i haven't tried this on pc bedrock so Idk if it still will work). Mojang please fix this!!!
. as I was about to create the issue I tried to see if it still will work on creative and certainly, it did work the only problem was that it didn't actually let you fly through blocks you were only able to go through 1 block and on that 1 block you would get stuck  ( on creative while flying you won't actually get stuck it would just make you fall down from the block on survival. I tried restarting Minecraft and leaving and that does fix it but if you die by drowning again you still will be able to go through block and another thing is that it only happens if you dive on the water and with dive I mean to get the laying down animation that makes you swim fast. You can only get this bug by dying to either drowning or a mob and only if you died while diving on the water, I also tried this in multiple blocks like oak wood planks stone dirt oak leaves, and much more and they all let go through the blocks
