RootView only accepts a single configuration source

[gimpel-cs]

I just reactivated a project where I used confuse 2.0.1. After updating to confuse 2.2.0, when creating a RootView instance from two SourceYaml instances, only the first one is taken into account. (Windows 11 pro, Python 3.14.2)

cfg1.yaml

group_1:
  item1: item_1.1
group_2:
  item1: item_2.1

cfg2.yaml

group_3:
  item1: item_3.1

import confuse

cfg1_source = confuse.YamlSource("cfg1.yaml")
cfg2_source = confuse.YamlSource("cfg2.yaml")
root_view: confuse.RootView = confuse.RootView([cfg1_source, cfg2_source])

print(root_view.get().items())

Output

dict_items([('group_1', OrderedDict({'item1': 'item_1.1'})), ('group_2', OrderedDict({'item1': 'item_2.1'}))])

From what I can tell, RootView.get has always returned just the first configuration. Just tested this on v1.7.0 and v2.0.1 and I get the same behaviour:

import confuse

cfg1_source = confuse.ConfigSource.of({
    "group_1": {"item1": "item_1.1"},
    "group_2": {"item1": "item_2.1"},
})
cfg2_source = confuse.ConfigSource.of({
    "group_3": {"item1": "item_3.1"},
})
root_view = confuse.RootView([cfg1_source, cfg2_source])

print(root_view.get().items())

dict_items([('group_1', {'item1': 'item_1.1'}), ('group_2', {'item1': 'item_2.1'})])
