Map with Id#0 duplicated several times after creating a new one from empty map in creative mode.
Step I used to reproduce the bug:
1. Create a new world
2. Get an empty map
3. right click on the empty map several times
Here's a step-by-step video
(I can't upload it here since it's a 150MB video)
I also found out that:
1. Map Id#0 contains nothing and won't work properly. But after relogging, it does contain something and works as intended.
2. After removing map Id#0, it doesn't duplicate anymore.

Resolved as duplicate of MC-162910, because that one seems to get updated more
Confirmed for 1.15 pre-6 in creative mode, and the map remains blank. In survival mode it works as intended.
