Would just like to note that this has occurred for me as well. It does not seem to matter what block type it is. I have been struck through my ceilings in areas of glass, planks, cobblestone and tree trunks. iOS 10.2.1 latest available game release at time of writing.

Can confirm this occurs for me as well

Can confirm this also happens for me and it's really annoying when trying to explore ocean monuments. Even adding water breathing and night vision etc makes next to no difference. Please could this get fixed. It seems to be somewhat of a longer standing issue judging by the report dates.
