Green item frame map marker is not removed in some cases

The bug

The green icon / marker displayed on a map when a copy of it is placed in an item frame is not removed in all situations.

 

I have found that this bug is present in all versions since 1.19 including the most recent pre release 1.19.4 Pre-release 3

Affected situations

• When punching out the map from the item frame
• When the item frames supporting block is removed

How to reproduce

1. Create a map
2. Place an item frame and place the map in it
3. Use one of the affected situations described above
4. See that the green icon remains even though the map is not inside the item frame anymore and/or the item frame is gone
