Please link to this comment in the description
The following is based on a decompiled version of Minecraft 1.10 using MCP 9.30.
The reason why this happens is very likely that the last position of the player is not updated when the player position is changed. More concrete, the server first receives packets and after that updates the player and updates its last position (method net.minecraft.network.NetHandlerPlayServer.captureCurrentPosition()):
The problem is that the method net.minecraft.network.NetHandlerPlayServer.setPlayerLocation(double, double, double, float, float, Set<EnumFlags>) which is used when the player used the chorus fruit (Update part) does not update the last player position (captureCurrentPosition()). When the client then sends the new position back, the server thinks the player teleported, because the last position was not changed in between.
