> while investigating an issue involving {{sling:alias}}, i inadvertently created nested alias i.e. ended up having an alias define for the parent and a child page.
> when looking at the values obtained from {{ResourceMapper.getAllMappings}}, i noticed that it only contains 1 combination. cross-checking however revealed that all combinations define valid paths that are properly resolved by sling.
> h5. Example
> parent: _/parent_ with alias name 'alias-parent'
> child: _/parent/child_ with alias name 'alias-child'
> valid paths for the child are (and expected from {{ResourceMapper.getAllMappings}}):
> - _/parent/child_
> - _/parent/alias-child_
> - _/alias-parent/alias-child_
> - _/alias-parent/child_
> actual values obtained from {{ResourceMapper.getAllMappings}}:
> - _/parent/child_
> - _/alias-parent/alias-child_
> consequently, an consumer of {{ResourceMapper.getAllMappings}} will miss valid alias path mappings. with additional nesting or addition of multiple alias values (see SLING-9620), the number of missed paths will increase.
