The bug:
In 24w37a, the map_id component allows items to become filled maps. However, different from the filled map, tooltips for the other items hides when advanced tooltips is shown.
Steps to reproduce:
Give a item with any map id.
/give @s diamond[map_id=0]
Open another empty map.
Enabled advanced tooltips and compare with each other.
Observed behavior:
The diamond only shows its name, while the filled map has ID, scaling, and level.
Expected behavior:
ID, scaling, and level are displayed on both items.
