[False positive] Jump report from using `Blink` above a pool of water on a flying mount

[Synful-Syn]

Current Behaviour

Moving forward and casting Blink (spell 1953) above a pool of water with a flying mount triggers a speedhack and an advanced jump alert.
Doing .anticheat player shows 2 counter measure and 1 jump reports.
I also sink at the bottom of the pool.

In worldserver.conf, I have MinWorldUpdateTime = 120 to simulate lag.
