[229982] water leeks even through water-block-tile

As the image below: RED water leeks through the cracking tile, AND through water-block-tile too. But the YELLOW there is no water leek (it's should not leek :D)

And when the cracking tile broke, no water leek anymore, just like the YELLOW

And luckily I've recorded the whole process, check the video I attached

Thanks <3 <3
