Review Comment:
`config.merge(['x.a': 'old'])` then `config.merge([x: ['a.b': 'new']])`
leaves the root alias `x.a` as `'old'`, while `navigate('x', 'a')` returns `[b:
'new']`. `getProperty('x.a', Map)` is then null.
Refresh the intermediate alias at the configuration root when a nested
dotted merge replaces a scalar with a map.
