This is the only test that fails prior to my fix, but I added the other subtests just to have some more comprehensive coverage, since there are currently no nested value tests at all.

f, err := LoadSources(LoadOptions{
AllowNestedValues: true,
}, []byte(`
[section]
key1 = value1
key2 =

[section2]
key3 = value3
`))
require.NoError(t, err)
require.NotNil(t, f)

assert.Equal(t, "value1", f.Section("section").Key("key1").String())
assert.Equal(t, "", f.Section("section").Key("key2").String())
assert.Equal(t, "value3", f.Section("section2").Key("key3").String())
})
