This needs to be fixed as soon as possible, since the export button in the world edit screen can't be shown anymore using texture packs which is a big problem for me, since that button is the only for me to get the file of a world to upload it (I'm making maps, on my android and can't get my worlds as files without that button)
I also just managed to reproduce this in 1.21.21 through the same way. The reason why you couldn't reproduce it may be because you made the "tube" too big, AFAIK the sponge should be able to "absorb" all the water, otherwise it won't work
I was able to reproduce it multiple times in different worlds, without any global resources or resource packs activated. It was on 1.21.20, I'm not sure if it was fixed in 1.21.21 already
I got this issue too yesterday. I've never been to the end.
I was playing in my world, made myself two bundles and put some items in there and then I got the "You need a mint" advancement..
