Publishing all languages to a new space ignores permalink option

When publishing a version with all languages, the permalink option is somehow ignored, i.e. it doesn't make a difference if it's selected or not...

Steps to reproduce:

• Create a space, create a version 1.0

• Select a default language and a second language

• Activate Permalinks (Duplicate Pagetitles)

• Create at least one page which is available in both languages

• Set a permalink for this page which is different to the original page title, e.g. permalink = "page123" and page title = "my page"

• Publish the version to a new space by selecting "All languages".

• Don't select "Keep Permalinks" on the options view

• Publish it and open the new space

Expected result:

• The permalinks are not copied to the new space, i.e. the page title of the original/default language will be used as the permalink

Actual result:

• The permalinks are copied to the new space, i.e. the permalink stays as "page123" and the page title stays as "my page"

Workaround:
Re-publish into the new space with "Publish into existing space" and by using the exact same options again.
