Put the summary of the bug you're having here
I was in creative mode building a house when I was flying and shifting while I was placing a hopper on a chest. when I unsifted I flew through the ceiling! Upon retesting, I noticed that this was reproducible and you could even go through multiple blocks. After even more testing, I was able to easily do this with the levitation effect too.
Steps to Reproduce:
-First, either fly or press yourself against a ceiling with levitation.
-Next, hold down shift (shift and space when flying).
-Lastly, release shift while flush to the block.
-You can repeat this while inside a block.
