This but is also on 1.21.71
And also, it's was not everytime that the player was launched 21 blocks, the average was 22.
For me it's the same, but even worse. It lags, I also did a bug report: https://report.bugs.mojang.com/servicedesk/customer/portal/6/MCPE-194334
I really hope this gets fixed, I made an entire map that is based on the mace. And it’s the reason why I am still playing the game.
It's indeed possible to be a intented behavior, as on bedrock for example, you can bridge while looking forward, while on java you can't! You can't say that something isen't right just because of a parity issue.
