Translation dialog does not create nested folders correctly

If you translate a document that is situated a nested folder structure, and the structure does not yet exist, the newly created structure is not created correctly. See screenshots of the dialog before creation, and of the result in the cms. When trying to translate another document from the same folder, the dialog does not understand the new structure anymore (see screenshot).

Reproduction path:
1. setup a new project from archetype version 2.00.02
2. update the pom to use <hippo.cms.version>2.26.08</hippo.cms.version>
3. build and run the project
4. use /essentials to add the News feature (no rebuild needed in this case)
5. in the cms add a new translated root folder (e.g. for the French locale)
6. set the new folder as a translation of the English folder
7. open a news document and translate it

See the screenshots for the results. Only the first two levels are created correctly. The third level is created as sibling and not as child of the second level. Also the fourth level (the document) is placed at the wrong level. The log shows this message:
