Description

According to the function help and documentation map_get(item_variables('Map 1'), 'map_scale') would help me retrieve the scale of a map item and use it for example in a label. This does no longer work unless I manually set the Item ID property of the map item, using only digits (eg. 1 or 124).
I'm not sure it makes sense and it's a nice UX to have for example my map named 1 instead of Map1 or my local map...

This works fine for me (and there's multiple unit tests protecting this) - can you attach a sample project?

Note that no items have an id by default - you always need to manually set ids.

Then what does represent the "Map 1", "Map 2" texts that appear at the top of the map item properties, and replaced by the "Item ID" when set? aren't they some kind of default internal IDs? Should they not be used for such a feature?
