Myself and players on my server are taking fall damage from multiple things.
Sprinting down stairs will cause fall damage.
Sprinting and jumping repeatedly will cause fall damage.
Climbing down a scaffolding tower will cause fall damage when you stop.
Several players have died due to this error, it's random and doesn't always occur. This is happening on multiple platforms and devices being used on the server.

I did not feel like this issue is the same as 120140.
In the server we do experience the same issue as building up and players being teleported off towers and taking fall damage but that is with this option "server-authoritative-movement=server-auth" or using "server-auth-with-rewind". However the problem I am explaining is not just taking fall damage while standing on a tower. I have also set the option to "client-auth" since there are so many problems with the "server-auth" option it's almost unplayable with that on.

Having also read the claims around desynching, I have to agree with Chris here. One key to this bug is that it links to the mini-animation (running, crouching, etc) seen in the top corner. If that animation is showing, everything done during that time in terms of y distance travelled (I leave that open as I haven't looked at +ve vs -ve contributions) appears to be bundled together.
As per my comment on MCPE-108459, although you may be travelling by means of scaffold or have your fall interrupted by a water source, you will still take damage and even die consistently. This behaviour is observed with BDS on 1.17.10.04
