the trolley drives through the blocks

DEVELOPERS PLEASE ATTENTION!!!!!!!!!!!!!!!!!Developers please fix this bug !!!!!!!

This bug begins when the rails and the trolley just appeared and so was not fixed in the pre-releases of Minecraft 1.14.1 and in previous updates, too. When you put the rails up and put the block down and when the trolley rolls to the bottom it passes through the block! The video shows everything shown. This bug is shown in the video. From above the trolley is the bottom of the block and now when the trolley goes down to the bottom along the rails it does not stop in front of it, but passes through the block!And the texture of the trolley becomes black!
