Water bucket doesn't work properly while on sneak and above an air block

Phone model: Lenovo A536

I tried placing water on the side of of a block I was standing on while my character was on the sneak position, before the update, I could do so as to create a waterfall that I could jump into to go down to a spot below the water fall.

I tried it just today and I thought I just wasn't pressing the side of the block right. After getting a better angle and making sure I could press the side of the block, the game would just react as if I was just tapping on the block with a tool or with bare hands and the water couldn't be placed.

This I believe is more to do with being unable to use a water bucket on the side of a block, while sneaking and having an air block underneath it. Once I placed a cobblestone block where I initially wanted the water to be in, I still couldn't place it from a distance. What I had to do was to step on top of the cobblestone block where I had wanted to put the water, and then jump and tap on top of the cobblestone to have the water be placed.

Unfortunately I can't get any screenshots as the volume down on my phone is faulty.
