Player launch animation not working reliably.

[zedwick]

With LaunchAndDropPlayers: true set in the config, players should be launched into the air prior to teleporting. However it seems this is not always true, and sometimes the player is not launched (but does drop post-teleport). The Ghast shoot sound does play, and there is a second delay before teleporting. With LaunchAndDropPlayers disabled, or if the player is flaying or not on the ground, neither of these would occur.

I have concluded that PD is running the code necessary to launch players into the air, but the velocity set on the player is sometimes being cancelled or otherwise not applied by the server.

I have only tested this with Paper version git-Paper-209 (MC: 1.16.3) (outdated). Need to confirm if this also occurs with the latest Paper, and with Spigot.
