Waterlogged blocks retain their waterlogged state when moved with sticky pistons with short pulse
The bug
Waterlogged blocks retain their waterlogged state when moved with sticky pistons with short redstone pulse. Screenshots attached.
Code analysis
The same code that fixed MC-127474 in TileEntityPiston.update() needs to be added to TileEntityPiston.clearPistonTileEntity() to ensure pistons that update faster than 2 ticks (or are quick-pulsed) also set their waterlogged state to false.
if(iblockstate.hasProperty(BlockStateProperties.WATERLOGGED) && iblockstate.getProperty(BlockStateProperties.WATERLOGGED)) { iblockstate = (IBlockState) iblockstate.withProperty(BlockStateProperties.WATERLOGGED, Boolean.valueOf(false)); }

I hope this function won't be removed either. I expect it will be useful for technical players.
This shouldn't be a bug. When sticky pistons are powered with a 0 tick pulse, the block they push is teleported. Water should remain in it. It is coherent with the behavior.
Confirmed for 1.16.3 and 1.16.4 RC1, although it shouldn't be considered a bug in the first place.
Can confirm in 1.17.1 and 21w37a.
