Spectator speed setting is not kept when relogging

When changing your speed in spectator mode using the scroll wheel it's not kept when you exit and reenter the world. That's not how I expected it to work and it's quite annoying when you're testing something that requires precise movement and it disappears after relogging.

Reproduction steps

• Go into spectator mode
• Use scroll wheel to change your speed
• Exit and reenter the world

Observed results

• Your flying speed has been reset

Expected results

• Your flying speed wouldn't be reset
