Discovered while testing MC-260812.
The bug
Tutorial hints will still remain in situations outside of normal gameplay, such as when leaving a world.
How to reproduce
Have tutorial hints show up, for example by creating a new launcher instance
Leave the world while one is present
Expected results
They would disappear once gameplay ends.
Actual results
They remain for a period of time.
This is essentially the same issue as MC-206344 but with the saving world screen. I've updated MC-206344 to mention that this also occurs with the saving world screen as well, so this ticket (MC-260813) can be resolved as a duplicate.
