Brief Description:
When I switched from Main to MainNorth, I fell and died. I know I was flying in both worlds, but when I joined MN, my /fly turned itself off for some reason. When I respawned after my death, my /fly was activated again without putting the command back

Instructions:
1.) Start in Main's Rising world (I did /kit anvil, /kit enderchest, then /tb commands too when I joined)
2.) Switch to MainNorth with /mn (In MN, /fly should be activated and should already be flying in the Rising world of MN)
3.) Fall on the ground and die

How many times did you recreate this?:
Only once

Result:
/fly deactivated and I died from fall damage

Expected Result:
/fly should be still on, or at the very least not take fall damage when I fall

Evidence:

 

I was still using 1.16.3. This was before the actual update.
