Entity(Chest boat) turning black while stuck in a block

Umm so this is my third bug report, and just want this bug to be fixed. So what happened?
I was trying something with the new chest boat, and it crashed into a wall. Then i was suffocating, with some bubbles(MCPE-34310) i guess? And the health was going down. So I got out of the boat instantly, and saw a black boat. So i tried remaking the glitch, and it sunk instead of having its chest sticking out of the block. So i tried to break the block next to it, and i saw a black thing resembling a boat in the block. So I broke the block, and the chest boat turned into the normal colour.
