Consequently, layers of part applied on top of this one must be invalidated and the OVERLAY step of these part re-executed. ### To Reproduce See `test_basic_lifecycle_actions` First run with: ``` parts: bar: after: [foo] plugin: nil foo: plugin: nil organize: '*': (overlay)/ ``` Then change it to: ``` parts: bar: after: [foo] plugin: nil foo: plugin: nil source: a.tar.gz organize: '*': (overlay)/ ``` The OVERLAY step of `bar` will be re-executed but it should. ### part yaml ```shell ``` ### Relevant log output ```shell N/A ```
