      The bug

      When a boat is falling while over a slime block, once it gets to about 5 blocks on top of the slime block, the boat will start rising and falling very slowly. As of 22w12a, this also occurs with boats with chests. As of 1.21.2 Pre-Release 2, the effect is not as large and does not occur with every bounce, but still happens.
