Problem/Motivation
Tests fail on schema for form field configuration using leaflet widget.
Steps to reproduce
This is an example of configuration exported
https://git.drupalcode.org/issue/geo_entity-3344453/-/blob/3344453-switc...
Running the test in that geo_entity_address submodule

I'll post a branch with all the schema items added, it was almost a cut & paste from field.formatter.settings.leaflet_formatter_default into field.widget.settings.leaflet_widget_default.
But while I was cutting and pasting my way through the fields in that entity_form_display configuration I started to questioning why some of the fields were there. Once I got to leaflet_popup I was wondering if I'd actually seen this in anything I could configure for the widget. Then at weight: null I was truly intrigued https://git.drupalcode.org/issue/geo_entity-3344453/-/blob/3344453-switc...
My assumption, without digging further, what is going on here is configuration that is or isn't actually used from LeafletSettingsElementsTrait?
Proposed resolution
Either add all the configuration schema for what is exported by the configuration item; or possibly thin it out a bit for stuff that's not actually used (if that's the case)?
Remaining tasks
Decide which is the best course forwards...
